Underground pipe line Information Management System Construction is just like a raging fire to be carried out in China, by building underground pipe line Information management system is able to satisfy the needs of work such as urban planning, construction, operation and emergency.One major tasks of system Construction It is exactly the bases such as the scale for grasping and acquiring in time underground utilities, positional relationship, functional attributes, property ownership, the operation time limit This information data.The a part of power high voltage pipeline as Underground Pipeline General Survey, cable are all placed in high-pressure well, and well lid is basic It is concrete material entirely, shape is mostly rectangle, and width about 0.5m, length is in 1.0m ~ 2m range, and thickness is in 0.08m ~ 0.25m model Enclose, quality is all heavier, high-pressure well it is densely distributed in city and extend range it is big, pipeline surveying work range it is wide, people The industry that works is very laborious time-consuming, even can not manually open sometimes.A kind of small-sized hoisting device is now designed, keeps operation time saving and energy saving fast Speed is convenient, while installation weight, within 50kg, universal wheel is arranged at bottom, and movement is got up easily fast, and manpower is greatly reduced Consumption, improve operating efficiency.The device can carry movement at any time, can be recycled.

Summary of the invention

In order to solve the above-mentioned technical problem, the utility model provides a kind of hoisting apparatus, and simple structure is low in cost, makees Industry is high-efficient, time saving and energy saving.

Technical solution adopted in the utility model is a kind of hoisting apparatus, including two upright bars, the top of two upright bars It is connected by upper beam, each self installation lower beam in the bottom of two upright bars, and the bottom of upright bar and the middle part of lower beam are fixed；Under The end of crossbeam passes through diagonal brace and is connected to upright bar；The upper beam is i-beam structure, I-steel upper beam as sliding rail, On two groups of pulley blocks being adapted to therewith are installed, every group of pulley blocks include the pulley that two pulleys are axially arranged along crossbeam, described The both ends of upper beam are additionally provided with spool, and spool is also connected with band handle knob, and steel wire one ends wound is another on spool It holds and is connect with the pulley close to the end；The device further includes the electric hoist below the pulley blocks, clamping plate by two groups of pulley blocks and Electric hoist is connected as one.

Further, there are two the universal wheels of strap brake for the bottom installation of each lower beam.

Further, which further includes snap ring and the wirerope for fixing weight to be lifted.

Further, the lower beam is perpendicular to upper beam and vertical rod designs.

Further, the upright bar and lower beam are channel steel, and diagonal brace is rectangle steel.

The utility model has the following beneficial effects:

1, small-sized weight is lifted by crane and is moved using device provided by the utility model, especially worked in Underground Pipeline General Survey In, high pressure well lid easily can be quickly opened, checks well gut line situation, work operations efficiency can be effectively improved, is ensured Safety reduces human input, and 3 ~ 4 number of every group that high pressure line can be made to generally investigate is significantly reduced to 1 ~ 2 people, there is certain economic effect Benefit.

2, more time saving and energy saving relative to pure manual work, more saved relative to mobile automobile crane artificial and equipment at This, operating efficiency is higher.And this device simple structure, it is low in cost, there is very big utility value in actual operation, over the ground High pressure well lid unlatching in underground pipelines generaI investigation has a clear superiority.

Detailed description of the invention

Fig. 1 is the structural front view of the utility model.

Fig. 2 is the structure top view of the utility model.

Fig. 3 is the structural side view of the utility model.

Specific embodiment

The utility model, but the range of the requires of the utility model protection are further illustrated below with reference to examples and drawings It is not limited to the scope of the embodiments.

As shown in Figure 1-Figure 3, the top of a kind of hoisting apparatus, including two upright bars 1, two upright bars is connected by upper beam 2 It connects, each self installation lower beam 3 in the bottom of two upright bars 1, and the bottom of upright bar 1 and the middle part of lower beam are fixed；The end of lower beam 3 Portion passes through diagonal brace 10 and is connected to upright bar；The upper beam 2 is i-beam structure, and I-steel upper beam is pacified thereon as sliding rail Equipped with two groups of pulley blocks 4 being adapted to therewith, every group of pulley blocks include the pulley that two pulleys are axially arranged along crossbeam, the upper cross The both ends of beam 2 are additionally provided with spool 5, and spool 5 is also connected with band handle knob 6, and steel wire one ends wound is another on spool It holds and is connect with the pulley close to the end；The device further includes the electric hoist 7 below the pulley blocks, and clamping plate 8 is by two groups of pulley blocks It is connected as one with electric hoist.

Preferably in scheme, there are two the universal wheels 9 of strap brake for the bottom installation of each lower beam 3.It being capable of basis It needs arbitrarily to advance and can be braked.

Preferably, which further includes snap ring and the wirerope for fixing weight to be lifted.Facilitate hoisting heavy.

Preferably, the lower beam is perpendicular to upper beam and vertical rod designs.

Preferably, the upright bar and lower beam are channel steel, and diagonal brace is rectangle steel.

When assembly, welding manner being all made of between column and upper beam, lower beam and diagonal brace and is fixed, connection is more Fastening.In use, the width direction along high-pressure well sheet block places hoisting apparatus, so that universal wheel is in braking state, use steel wire Rope is fixed wirerope with snap ring and is hung on electric block across the hoisting ring for being hung well lid, checks that each position connection is good Afterwards, it slowly opens electric block power supply and lifts by crane well lid, until stopping lifting after certain altitude, pulley row is controlled by band handle knob Into keeping the well lid sling mobile to predetermined direction, is braked after being moved to predetermined position, slowly open electric block power supply and put down well Lid is to settling position, so far high pressure well lid smooth safe opening, and operating personnel, which can enter in well, checks situation in well, measures Related data is surveyed and recorded, is measured after completing personnel safety out, closes well lid according to the reverse step for opening well lid.
