Description

Technical Field

[0001] The invention belongs to the technical field of lifting tools for hydraulic engineering equipment, and particularly relates to a lifting tool for opening and closing different hydraulic engineering equipment. Background Art

[0002] In the existing lifting tool technology, the end beam alignment device and the center of gravity adjustment device are both of fixed mechanical structures. The end beam alignment device and the center of gravity adjustment device can only be adjusted proportionally through mechanical transmission and cannot be adjusted separately, which is not flexible enough and has great limitations, and cannot fully meet the requirements of actual engineering use. Sometimes it is not only inconvenient to use but also technically infeasible.

[0003] The same lifting tool is usually used for multiple hydraulic engineering equipment with the same opening and closing center of gravity. For hydraulic engineering equipment with different centers of gravity, different lifting tools must be used in combination for opening and closing. In actual engineering, there are difficulties such as a large amount of operation and maintenance work, inconvenient storage, and inconvenient use. Summary of the Invention

[0004] The purpose of the invention is to provide a lifting tool for opening and closing different hydraulic engineering equipment, and the same lifting tool can be used to open and close hydraulic engineering equipment with different centers of gravity.

[0005] To achieve the above invention purpose, the invention provides a lifting tool for opening and closing different hydraulic engineering equipment, which includes a beam body, a lifting lug on the upper side of the beam body, a threading and detaching shaft device connected to the hydraulic engineering equipment on the lower side of the beam body, and end beam alignment devices are further arranged at both ends of the beam body. The end beam alignment device includes: a box-shaped end beam, which is vertically installed at both ends of the beam body and can move relatively; a guiding device, which is fixedly installed on the end beam and cooperates with the gate slot on the outside; an adjusting device, which is fixedly installed in the box-shaped end beam and is used to adjust the relative position between the beam body and the guiding device on the end beam to adapt to hydraulic engineering equipment with different lifting centers of gravity and to adjust the center of gravity of the lifting tool.

[0006] Further, installation holes are provided at both ends of the beam body, and guiding plates are arranged at the four corners of the installation holes. The end beam is arranged in the moving channel surrounded by the guiding plates, and the end beam can move in the moving channel.

[0007] Further, the adjusting device is a counterpoint hydraulic press with one end fixed to the end beam and the other end fixedly connected to the beam body, and a counterweight hydraulic press with one end fixed to the end beam and the other end fixedly connected to a counterweight block. The counterpoint hydraulic press and the counterweight hydraulic press are arranged in the box-shaped end beam and can be controlled separately. The counterweight block is arranged in the box-shaped end beam and can move relatively to the inner wall of the end beam.

[0008] Further, guiding plates are provided at the four corners of the counterweight block on the end beam to form a moving channel for the counterweight block.

[0009] Further, the counterpoint hydraulic press and the counterweight hydraulic press are arranged vertically and parallel to each other along the longitudinal direction of the end beam, without interfering with each other and occupying little space.

[0010] Furthermore, inside the cavity between the front and rear mounting holes of the beam body, there is a fixed shaft fixed to the beam body. The alignment hydraulic press is fixedly connected to the fixed shaft. There are longitudinal elongated holes on the end beam, and both ends of the fixed shaft can move in the elongated holes for limiting the movement of the end beam.

[0011] Furthermore, the guiding device includes two pairs of guiding columns fixedly connected to the end beams on both sides of the beam body, and guiding rods vertically fixed to the guiding columns. There are sliding blocks at the positions where the guiding rods cooperate with the door grooves.

[0012] Furthermore, on the outer sides of the front and rear guiding columns, there are side wheels facing both sides. The extending ends of the side wheels extend outside the end beam to ensure that the spreader does not get stuck during lifting and lowering operations.

[0013] The spreader for opening and closing different hydraulic equipment of the present invention has the following advantages compared with the prior art:

[0014] (1) The alignment device at the end of the spreader can adjust its position through the adjusting device to adapt to hydraulic equipment with different lifting centers of gravity, and enable the spreader to smoothly enter the slot. The adjusting device can also adjust the position of the counterweight block to make the whole spreader in a balanced state. The positions of the alignment device and the counterweight block can be adjusted separately, with high precision and high flexibility, solving the problem that the spreader in the prior art cannot open and close hydraulic equipment with different centers of gravity.

[0015] (2) The support guiding device (including guiding columns, guiding rods and sliding ways) and the side wheel device are arranged on the end beam alignment device, with a compact structure. It can ensure that the spreader smoothly enters the slot without getting stuck.

[0016] (3) This technical invention has the advantages of being safe and reliable, convenient to adjust, technologically advanced, saving investment, and being easy to install and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a hanger for opening and closing different hydraulic equipment of the present invention in conjunction with the accompanying drawings.

[0030] like Figure 1 The upper side of the beam body 2 of the lifting device for opening and closing the hydraulic equipment shown is hoisted on the lifting equipment 6 through the lifting ear 5, and a threading and detaching shaft device 7 is provided on the lower side of the beam body 2 to be connected to the gate 10. A sensor device 8 is provided at the lower end of the lifting ear of the threading and detaching shaft device 7. An alignment device 9 is also provided on the lower side of the beam body 2 for positioning when the threading and detaching shaft device 7 is connected to the hydraulic equipment 10. End beam alignment devices 1 are provided at both ends of the beam body, and a waterproof and pressure-resistant sealing plug 3 and a hydraulic pump station device 4 are also provided in the middle position of the beam body to provide power.

[0031] like Figure 1 、 Figure 3 and Figure 6As shown in the figure, the end beam alignment device 1 includes an end beam 106. The end beam 106 is box-shaped and horizontally passes through the mounting holes at the ends of the beam body 2 that match it, and the end beam 106 is perpendicular to the beam body 2. Support plates 115 are fixedly arranged on the left and right sides outside the front and rear two mounting holes, flush with the inner sides of the mounting holes, and reinforcing plates 116 are vertically arranged on the outside of the support plates. Two support columns 117 are arranged above and below the outside of the two mounting holes, and a through guide plate I 118 is arranged on the support plates 115 and the support columns 117. The end beam is arranged in the moving channel surrounded by the guide plate I 118 and is used as a guide when the end beam moves.

[0032] As Figure 3 shown in the figure, a guiding device is fixedly arranged on the upper surface of each end beam 106 on both sides of the beam body 2. Each guiding device includes a vertically upward guiding column 103. A guiding rod 102 is vertically arranged at the upper end of the guiding column 103, and the guiding rod 102 extends to the left and right sides of the spreader. Two guiding rods are also arranged at the relative positions of the end beam 106 and the aforementioned guiding rod 102. Sliders 101 are fixed at the ends of the four guiding rods 102 facing the direction of the portal groove 11, and the sliders 101 play a guiding role during the process of the spreader entering the portal groove 11.

[0033] As Figure 4 shown in the figure, side wheels 104 facing the outside are fixed on the front and rear sides of the guiding column 103, and the extending ends of the side wheels 104 extend outside the end beam 106. In this way, during the process of the spreader entering the portal groove 11, the side wheels 104 first come into contact with the side surface of the portal groove 106 to ensure that the spreader does not get stuck during lifting and lowering operations. The outer wall of the end beam below the side wheels is removed to make room for the installation of the side wheels.

[0034] As Figure 3 Figure 4 shown in the figure, a counterweight 112 is arranged at one end inside the box-shaped body of the end beam 106. The four edges of the counterweight 112 are guided by L-shaped guide plates II 119 fixed on the inner wall of the end beam 106 and can move along the length direction of the box-shaped body of the end beam 106. A stop block 120 for restricting the stroke of the counterweight is arranged at the end of the end beam. An adjusting device is arranged along the length direction of the box-shaped body inside the box-shaped body of the end beam 106. The adjusting device includes: an alignment hydraulic press 107, one end of the alignment hydraulic press 107 is fixed on the end beam, and the other end is fixed on the beam body. The alignment hydraulic press can drive the end beam 106 to move back and forth in the two mounting holes of the beam body 2; a counterweight hydraulic press 108, which is arranged in parallel with the alignment hydraulic press 107 inside the box-shaped body of the end beam 106. One end of the counterweight hydraulic press 108 is fixed on the end beam, and the other end is fixed on the counterweight 112. The counterweight hydraulic press 108 can drive the counterweight 112 to move inside the box-shaped body of the end beam 106. Both ends of the alignment hydraulic press 107 and the counterweight hydraulic press 108 are fixed by hydraulic press lifting heads 110, 111, 113.

[0035] As Figure 3 、 Figure 4 and Figure 9As shown, on both sides of the installation hole position of the beam body 2 near the assembled end beam 106, a mounting plate 121 fixed to the upper and lower inner walls of the box body is provided. A fixed shaft 114 is installed between the mounting plates 121. The direction of the fixed shaft 114 is perpendicular to the center connection line of the two installation holes. The end beam is provided with an elongated hole 105, preferably an oblong hole, at the position of the fixed shaft 114, which is used to define the limit position of the movement of the end beam. The connection between the alignment hydraulic press 107 and the beam body 2 is installed on the fixed shaft 114 through bearings. The width of the mounting plate 121 is smaller than the width of the end beam box body, and there is a gap between the fixing plate and the two side walls for convenient assembly. A reinforcing plate 122 is provided outside the mounting plate 121.

[0036] As Figures 3 to 5 , Figure 7 and Figure 9 shown, one end of the alignment hydraulic press 107 and the counterweight hydraulic press 108 is fixed to the end beam 106. The specific connection method is to set two fixing plates 109 fixed to the upper and lower inner walls and parallel to the side walls at the end of the end beam 106 away from the counterweight 112. The hydraulic press lifting head 113 is fixed between the two fixing plates 109, and the alignment hydraulic press 107 and the counterweight hydraulic press 108 are installed parallel up and down.

[0037] As Figure 7 and Figure 10 shown, the lifting device of the opening and closing hydraulic equipment in this embodiment is used to open and close five sections of gates respectively, namely the top section gate and the first to fourth section gates. The positions of the lifting center line 13 - 17 and the orifice center line 12 are as Figure 7 shown. The position of the lifting center line of each section of the gate is accurately positioned and adjusted by the alignment hydraulic press 107. The lifting device is aligned with the corresponding lifting position outside the gate slot 11, and the counterweight hydraulic press 108 in the end beam 106 is used to adjust to make the whole lifting device in a balanced state. On the one hand, it ensures the mating connection between the lifting device and the gate 10, and on the other hand, it ensures no jamming when mating with the gate slot 11. After adjusting the balance, the opening and closing operation is carried out to make the lifting device enter or exit the slot.
