Description

Technical Field

[0001] This utility model relates to the field of lifting technology for plastic pipes and fittings, and in particular to a vertical transport lifting device for pipes and fittings. Background Technology

[0002] Currently, in industrial construction projects in the petrochemical field, for highly corrosive processes, the design typically uses plastic process pipes. These pipes are large, lightweight, and compact, with limited space and restricted operation. While large machinery can be used for hoisting in the early stages of construction, in the later stages, due to space constraints, the prefabricated pipes and fittings can only be transported manually using hand-operated hoists. However, because the load-bearing points of the hand-operated hoists need to be changed frequently during operation, they need to be disassembled and re-attached in new locations, resulting in low efficiency.

[0003] Therefore, there is an urgent need for a vertical transport hoist that can provide an installation location for the hand chain hoist and flexibly adjust the working position of the pipes and fittings according to the work requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical transport lifting device for pipes and fittings, which can provide an installation position for a hand chain hoist and can flexibly move and adjust the working position according to the lifting requirements, avoiding the tedious operation of frequent disassembly and installation of the hand chain hoist, effectively reducing labor intensity and improving work efficiency.

[0005] The present invention adopts the following technical solution:

[0006] A vertical transport lifting device for pipes and fittings includes a lifting beam, with a lifting lug at one end of the lifting beam for mounting lifting tools, and a clamping plate at the end of the lifting beam away from the lifting lug, forming an mounting groove between the clamping plate and the bottom of the lifting beam.

[0007] Preferably, the length of the lifting beam is adjustable.

[0008] Preferably, the lifting beam includes a bottom bracket, and the card plate is fixedly disposed at one end of the bracket; a movable frame is slidably disposed on the bracket, and the lifting lug is disposed at the end of the movable frame.

[0009] Preferably, the bracket, the movable frame, and the card plate are all made of angle steel.

[0010] Preferably, the movable frame and the bracket are provided with a movable groove on the side away from each other, and the bottom of the movable frame and the top of the bracket are rotatably provided with rollers, which are movably located in the movable groove.

[0011] Preferably, a screw is coaxially mounted on one end of the roller shaft located outside the moving groove, a locking plate is sleeved on the screw, and an adjusting nut is mounted on the screw shaft outside the locking plate; wherein the length of the roller shaft is not greater than the width of the moving groove.

[0012] Preferably, the two rollers are arranged diagonally.

[0013] Preferably, the bottom of the card plate is provided with a locking bolt.

[0014] Preferably, a limiting disk is provided on the roller shaft, and the limiting disk is located inside the moving groove.

[0015] Preferably, both the card plate and the bottom of the bracket are provided with rubber gaskets.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model can install the lifting beam by setting a clamping plate at the end of the lifting beam and using the installation groove formed between the clamping plate and the lifting beam to clamp onto the pipe gallery structural beam; the lifting operation can be carried out by setting a hand hoist on the lifting lug; when it is necessary to change the lifting position, it is only necessary to control the lifting beam to move along the length of the pipe gallery structural beam. The operation is simple and quick, without the need for frequent disassembly, reducing labor intensity and improving work efficiency. Attached Figure Description

[0020] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0021] like Figures 1 to 3As shown, the present invention discloses a vertical transport lifting device for pipes and fittings, comprising a lifting beam 1, with lifting lugs 2 at one end for mounting lifting tools (typically using a hand-operated hoist), and a clamping plate 3 at the end of the lifting beam 1 away from the lifting lugs 2. A mounting groove 4 is formed between the clamping plate 3 and the bottom of the lifting beam 1. The lifting beam 1 is secured to a pipe rack structural beam via the mounting groove 4. The pipe rack structural beam is made of steel profile, and the mounting groove 4 engages with the flange plate of the steel profile, thus installing the lifting beam 1. The main body of the lifting beam 1 rests on the pipe rack structural beam, which provides support. Compared to existing technologies where a hand-operated hoist is directly tied and installed at the working position, this invention allows for flexible adjustment of the lifting point. When the lifting point needs to be changed, only the lifting beam 1 needs to be moved along the length of the pipe rack structural beam. The operation is simple and quick, eliminating the need for frequent disassembly, reducing labor intensity, and improving work efficiency.

[0022] Furthermore, in this embodiment, the length of the lifting beam 1 is adjustable to expand its application range and enhance the flexibility of the lifting equipment. Specifically, the lifting beam 1 includes a bottom bracket 1-1, and a clamping plate 3 is fixedly installed at one end of the bracket 1-1 by welding; a movable frame 1-2 is slidably mounted on the bracket 1-1, and a lifting lug 2 is located at the end of the movable frame 1-2. The bracket 1-1, movable frame 1-2, and clamping plate 3 are all made of angle steel, which is readily available and inexpensive. In addition, as... Figure 2 As shown, a moving groove 5 is provided on the side of the moving frame 1-2 and the bracket 1-1 that are far apart from each other. The moving groove 5 is provided on the side wall of the moving frame 1-2 and the bracket 1-1 and is opened along the length of the side wall of the moving frame 1-2 and the bracket 1-1. An installation rod 6 is fixedly provided at the bottom of the moving frame 1-2 and the top of the bracket 1-1. A roller 7 is rotatably provided on the installation rod 6 through a bearing. The roller 7 is movably located in the moving groove 5. The length adjustment of the lifting beam 1 is achieved by sliding the roller 7 within the moving groove 5 to move the moving frame 1-2 relative to the bracket 1-1. The two rollers 7 are arranged diagonally, with the roller 7 on the moving frame 1-2 located in the moving groove 5 of the bracket 1-1 near the clamping plate 3, and the roller 7 on the bracket 1-1 located in the moving groove 5 of the moving frame 1-2 near the lifting lug 2, ensuring that the adjustment of the moving frame 1-2 is not affected. Since the weight of the pipe being lifted is not large, and the required adjustment length of the lifting beam 1 is not excessive, only one roller 7 can be set on each side, or two rollers can be set side-by-side, depending on the actual working conditions. Furthermore, in this embodiment, when the bracket 1-1 and the moving frame 1-2 are connected, their end faces are in contact with each other, i.e., the bottom of the moving frame 1-2 overlaps the top of the bracket 1-1, ensuring that the moving frame 1-2 transmits force to the bracket 1-1 and the lower pipe gallery structure beam during lifting. Avoid applying too much force to the moving frame 1-2 onto the roller 7, and then transmitting it downwards through the roller 7.

[0023] Furthermore, a screw 8 is coaxially mounted on one end of the roller shaft 7 outside the moving groove 5. A locking plate 9 is sleeved on the screw 8, and an adjusting nut 10 is mounted on the screw 8 outside the locking plate 9. The length of the roller shaft 7 is not greater than the width of the moving groove 5 to avoid affecting the displacement of the locking plate 9. After the moving frame 1-2 is adjusted into place, rotating the adjusting nut 10 moves it axially along the screw 8 to push the locking plates 9 on both sides against the side walls of the corresponding bracket 1-1 and the moving frame 1-2 respectively, thus completing the positioning and fixing of the moving frame 1-2 and ensuring the stability of the moving frame 1-2 during operation. In addition, a limit plate 11 is also provided on the roller shaft 7. The limit plate 11 is located inside the moving groove 5 and can laterally limit the moving frame 1-2 to prevent the moving frame 1-2 from shaking laterally and ensure the stability of the moving frame 1-2.

[0024] Furthermore, rubber gaskets 12 are provided at the bottom of both the clamping plate 3 and the bracket 1-1 to improve the tightness of contact with the pipe rack structural beam and reduce wear on the pipe rack structural beam during movement. Locking bolts 13 are threaded at the bottom of the clamping plate 3. If there is a gap between the mounting slot 4 at the installation position and the flange plate of the pipe rack structural beam, the locking bolts 13 can be adjusted to abut against the flange plate to complete the positioning and fixing of the lifting beam 1, ensuring the stability of the lifting beam 1.

[0025] This utility model has a simple structure and is easy to operate. By setting a clamping plate 3 at the end of the lifting beam 1, the installation groove 4 formed between the clamping plate 3 and the lifting beam 1 can be used to clamp onto the pipe gallery structural beam, thus realizing the installation of the lifting beam 1. The lifting operation can be carried out by setting a hand hoist on the lifting lug 2. When it is necessary to change the lifting position, it is only necessary to control the lifting beam 1 to move along the length of the pipe gallery structural beam. The operation is simple and quick, without the need for frequent disassembly, effectively reducing labor intensity and improving work efficiency.
