Description
Technical field
The utility model relates to a kind of lifting appliance, and especially a kind of being used for lifted by crane isolated plant when small distribution voltage transformer (abbreviation distribution transforming) overhauls, and belongs to the weight-lifting equipment technical field.
Background technology
A large amount of small-sized distribution transforming (as the 10kV distribution transforming) is arranged, at nearly ten million platform that has of whole nation use at present in distribution of vast rural area and urban distribution network.Annual power supply department repair and maintenance task is very heavy, a lot of distribution transformings are according to customer requirement, must be installed in the place of various complexity and remote rural area, as the distribution transforming on the distribution transforming of installing on the H-frame pole framework in city, the rural area and the rural area electrified irrigation water drainage station cement stylobate.Because road problem, crane and elevator machinery are difficult to arrive the place, distribution transforming place that needs maintenance, therefore be necessary to propose a kind of convenient transportation, be fit to the lifting appliance of small-sized distribution transforming.
The utility model content
The purpose of this utility model is: at above distribution transformer lifting demand, a kind of small-sized distribution transforming lifting appliance is proposed, this device should simple and convenient assembly, transportation is light, emergency capability is strong, can't arrive needing of local small-sized distribution transforming maintenance lifting thereby satisfy large lifting equipment, use manpower and material resources sparingly simultaneously.
In order to reach above purpose, small-sized distribution transforming lifting appliance of the present utility model comprises by lifting beam captives joint the gallows frame that constitutes with two fixed legs and lifting arm, described lifting arm plug-in mounting is fixed in the endoporus of fixed leg, the lower end of described two fixed legs is fixed on the end crane span structure, on the described lifting beam jack is installed, the universal adjustment head is housed on the described jack, connects two ends in the described universal adjustment head and lead the cable wire that hangs regulating plate by coupling link.
During use, the end crane span structure that supports gallows frame is fixed on the electric pole that distribution transforming is installed on metal bin or the stylobate, after installing lifting such as jack facility, suspended core on regulating plate and the distribution transforming case lid is connected, can slowly rise distribution transformer by pressing jack, make it to be installed to the desired position, very convenient.
Small-sized distribution transforming lifting appliance of the present utility model is small and exquisite flexibly, convenient transportation, therefore can be widely used in the narrow and small place that complex-terrain that mechanical crane can not put in place or mechanical crane can not play a role, and the place that needs the high-altitude lifting, a large amount of manpower and materials can be saved.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the folded state scheme drawing of Fig. 1 embodiment.
The scheme drawing that Fig. 3 lifts on bar for Fig. 1 embodiment.
Fig. 4 lifts scheme drawing for Fig. 1 embodiment on stylobate.
The specific embodiment
Embodiment one
The small-sized distribution transforming lifting appliance of present embodiment as shown in Figure 1, the upper end of two lifting arms 4 is shaped on fixed orifice, the two ends of lifting beam 1 penetrate from the fixed orifice of two lifting arms respectively, by bolt.The lower end of lifting arm 4 is inserted in two fixed legs 3, is shaped on upper and lower a plurality of knock hole on the fixed leg 3, can constitute gallows frame according to the hoisting height needs by inserting fixedly lifting arm of steel pin 12.The lower end of two fixed legs 3 is fixed in the spacing track of end crane span structure 2.The middle part of lifting beam 1 installs and fixes jack 11, and universal adjustment 9 is equipped with in the upper end of jack 11, connects cable wire 7 in the perforation of this universal adjustment 9, and these cable wire two ends are led by coupling link 14 and hung the regulating plate 8 that is shaped on some connecting bores.
In addition, the small-sized distribution transforming lifting appliance of present embodiment also has following constructional feature:
1, the walking stabiliser 6 that end crane span structure 2 two ends can the mounting strap wheel, so that the shift position, roller is equipped with in this bottom, walking stabiliser two ends, uses bolt after can embedding end crane span structure in the groove at middle part.Time spent not, can left-hand thread on end crane span structure, wheel is up;
2, crane span structure 2 bottoms in the end are furnished with support connecting element 5, can constitute holding device by bolt and end crane span structure when needed, are fixed on the metal bin;
3, is furnished with the support adapter 10 that can support hanging beam, so that regulate the height of lifting arm at needs by the supplemental support facility.
Distribution transforming 2 maintenance that are used on the type electric pole 1 are lifted by crane as shown in Figure 3, earlier end crane span structure is passed above the metal bin of door type electric pole and between the distribution transforming below, after again the support connecting element being put into below metal bin, pass the long lumbar hole of end crane span structure and metal frame and connecting element both sides successively with two single ended bolt, clamp respectively with double nut then.Groove both sides from end crane span structure push two fixed legs respectively, according to the size of distribution transforming maybe needs regulate the distance that pushes, side socket in advance promotes post on fixed leg, promote column sleeve be connected on collapsing length in the fixed leg can be in advance according to the height of distribution transforming maybe needs regulate, regulate the back and insert with location steel Xiao in the knock hole of fixed leg and fix.Lifting beam is penetrated from the hole that promotes the column top, the screwed in place bolt installs jack and universal adjustment head, cable wire, regulating plate at last on lifting beam, can lift by crane and operate again.
During lifting, cable wire one end and distribution transforming case lid upper suspended core device are connected, press jack, after the suspended core device hangs high certain altitude (for example 150 millimeters), just can be in distribution transforming along sleeper on two headrests and install support adapter.As the suspended core insufficient height, can shake after support adapter raises, regulate promoting post and carry out secondary hydraulic pressure top and hang again, repeatedly repeat to change the suspended core height in case of necessity, can realize the lifting of desired height.
When the small-sized distribution transforming lifting appliance of present embodiment is used to be contained in distribution transforming maintenance lifting on level land or the cement stylobate, as shown in Figure 4, different is: earlier end crane span structure is passed from the footing center between distribution transforming and level land or the cement stylobate, other is identical with said process.
Not the time spent, the small-sized distribution transforming lifting appliance of present embodiment can be as shown in Figure 2, and folding is got up, and tightens with the nylon cingulum, and transportation is preserved all very convenient.
After adopting small-sized distribution transforming lifting appliance of the present utility model, can be in complex-terrain or the narrow and small place that mechanical crane can not put in place, and lifting operation is finished in the place, high-altitude, therefore has the high acute and high efficiency of answering, and assembly and disassembly and transport easy, both quick, safety, time saving and energy saving again.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
