Embodiment 1

[0014] Such as figure 1 The large-scale pump body safety hoisting tool used for oil transportation includes a balance board 1 and a hook 9, a weight block 5 is provided at the upper end of the middle part of the balance board 1, and a lifting ring 4 is provided at the upper end of the weight block 5, and the balance board 1 Both ends of the weighting block 5 are provided with card notches 2 in the axial direction, and hooks 9 are arranged in the said card notches 2 at both ends. Connect and pass through the hook rod of the card notch 2, the hook rod is covered with a lock nut 8, the upper end of the hook rod is provided with a threaded section that cooperates with the lock nut 8, and the lower end of the hook rod is provided with an arc-shaped hook Body 11.

[0015] When using this embodiment, first adjust the distance between the two hooks 9 so that the two hooks 9 are respectively hung on the liquid inlet and the liquid outlet at both ends of the pump body. The locking nut...

Embodiment 2

[0018] In this embodiment, the following structure is added on the basis of the embodiment 1, specifically: the inner arc surface of the hook body 10 is provided with an anti-slip groove 10 .

[0019] In this embodiment, the inner arc surface of the hook body 10 is directly in contact with the pump body. In order to prevent the pump body and the hook body 10 from sliding against each other during hoisting, which will affect the safety of hoisting, an anti-skid groove 10 is added to increase the friction. Force, can guarantee the relative stillness of pump body and hook body 10, make pump body more stable.

Embodiment 3

[0021] In this embodiment, the following structure is added on the basis of embodiment 1 or embodiment 2, specifically: a nameplate groove 6 is also provided on the front end surface of the middle part of the balance board 1 .

[0022] In this embodiment, in order to facilitate hoisting personnel to choose hoisting tools of appropriate strength to hoist pump bodies of different weights, a nameplate groove 6 is specially set on the front face of the middle part of the balance plate 1, and the maximum hoisting capacity of the hoisting tool can be inserted in the nameplate groove 6. , the maximum distance between the hooks 9, the usage and other basic information, which is convenient for hoisting personnel to choose.

Abstract

The invention discloses a safety hoisting tool for large-sized pump bodies applied to petroleum transportation. The safety hoisting tool comprises a balance plate and pothooks, wherein a weighting block is arranged at the upper end of the middle part of the balance plate; a hoisting ring is arranged at the upper end of the weighting block; the balance plate is provided with clamping notches at the two ends of the weighting block along the axial direction; the pothooks are arranged in the clamping notches of the two ends; each pothook comprises a fixture block clamped at the upper end of the clamping notch and a pothook rod connected to the fixture block and passing through the clamping notch; a locknut is sleeved on the pothook rod; a thread segment matched with the locknut is arranged at the upper end of the pothook rod; and pothook bodies are arranged at the lower ends of the pothook rods. The safety hoisting tool has the beneficial effects that the interval between the pothooks can be adjusted according to the pump bodies of different sizes, thereby meeting the hoisting of the pump bodies of different sizes, after hoisting, the pothooks are locked through the locknuts, do not shift and are safe for the pump bodies, and the safety hoisting tool is stable in structure on the whole during hoisting, does not cause the rotation of the pump bodies and is good in hoisting safety and stability.

Description

technical field [0001] The invention relates to a processing auxiliary part, which belongs to the field of machinery, in particular to a safety hoisting tool for a large pump body used for oil transportation. Background technique [0002] In petroleum, metallurgy, construction, chemical industry and other fields, some large booster pumps and high pressure pumps are used to meet the needs of some equipment and the transportation of materials. When lifting and transporting some large pump bodies, due to their large weight, Generally, it is connected with a crane or a hook by a steel rope. When using a steel rope for hoisting, it is necessary to use steel ropes of different diameters and lengths to meet the stress requirements for each pump body of different weight and size. , is very troublesome, and because the steel rope is extremely inconvenient, it is time-consuming and labor-intensive. At the same time, after a long-term use of the steel rope, large and small iron thorns ...
