Abstract
The utility model relates to a high-voltage iron tower live lifting up device which comprises four self-climbing type lifting up frames mounted in the pedestal of the iron tower. Each lifting up frame is provided with a hydraulic jack; the two hydraulic jacks including a large hydraulic jack and a small hydraulic jack at each pair of diagonal angle positions form a hydraulic jack group, wherein the hydraulic oil output ports of the large hydraulic jacks are connected with the hydraulic oil input ports of the small hydraulic jacks through oil pipes; and the lifting heights of the hydraulic stems of the large hydraulic jacks and the small hydraulic jacks are synchronous. In the four jacks, the two jacks including a large jack and a small jack at each pair of diagonal angle positions form a jack group and specifically connected together through the oil pipes, so the hydraulic stems of the two jacks of each group have synchronous lifting strokes during working, the control accuracy is improved, and the stability of the tower frame is improved in construction.
Description
Technical field
The utility model relates to a kind of jacking engineering equipment, the charged lift-up device of particularly a kind of high voltage iron tower.
Background technology
Be set up in open-air high voltage iron tower between in use long after, because the landforms of iron tower periphery change, the a large amount of backfill that produce during as land development etc., phenomenons such as sedimentation can appear in some iron tower, cause the stressed of iron tower to change, the safety of iron tower is a greater impact, if thoroughly do not handle, meet bad weather condition, the incident that is easy to collapse, in addition, because the needs of building, as the setting up of speedway, soil raising etc., cause the insufficient height of transmission line of electricity, overhead wire need be raise.In order to address the above problem, traditional way is upright again aside iron tower, and old line is removed, set up on the new iron tower, by replacing old tower to solve this problem with new iron tower, this mode not only cost is big, but also need the power failure operation, can impact to the user.To this, the applicant has applied for that in 2003 the patent No. is 03113724.5 patent of invention " the self climbing type pole raising method of a kind of self climbing type pole lift-up device and high voltage iron tower ", utilize four the self-climbing jacking frames being installed on respectively in the iron tower pedestal and the jack of relative set under situation about need not cut off the power supply, directly former iron tower to be carried out jacking, solved the problems referred to above.But when practical application, owing to be the independently controls separately of four jack, and when work compound, it is synchronous that the lifting stroke of each jack expansion link all need keep, required precision to control is higher since the weight of iron tower greatly, highly high, it is subjected to the interaction of various external force such as wind-force, wirerope pulling force in by the jacking process, make the stressing conditions complexity, and in above-mentioned patent, there is no the stability problem of open solution iron tower in the jacking process.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of good stability, control accuracy height, can charged jacking the high voltage iron tower lift-up device.
The technical scheme that the utility model adopted is:
The charged lift-up device of a kind of high voltage iron tower, it comprises four self-climbing jacking frames that can be installed on respectively in the iron tower pedestal, each jacking frame is equipped with hydraulic jack, two hydraulic jack at every intersection diagonal angle are formed the hydraulic jack group by large and small two respectively, wherein the hydraulic oil delivery outlet of big jack is connected by oil pipe with the hydraulic oil input port of little jack, and it highly is synchronous that the hydraulic stem of described large and small jack raises.
Further improvement of the utility model, in above-mentioned two groups of jack groups, hydraulic pressure control device fuel feeding in parallel is concentrated by one in the hydraulic oil input port of these two big jack.
The beneficial effects of the utility model are: four jack that are used for promoting iron tower, each intersects two jack at diagonal angle and forms one group and by the specific connection of oil pipe by large and small different jack respectively, make two jack its hydraulic stem when work of every group have synchronous lift, stability of tower when having improved control accuracy and construction; In addition, in order to make the balance of iron tower when working better, the utility model also is provided with a centralized hydraulic pressure control device, its fuel feed pump is connected in parallel in the hydraulic oil input port of two big jack, when iron tower is applied to wherein pressure on one group of jack and increases, this pressure reaches another group jack by the oil feeding line of parallel connection simultaneously, the pressure of iron tower is evenly born by four jack, thereby the balance that as far as possible keeps iron tower when making the jacking operation, the design's lift-up device has guaranteed that iron tower is in charged jack-up construction process safe because balance is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that lift-up device is loaded on the schematic diagram in the iron tower pedestal;
Fig. 2 is that lift-up device is loaded on the schematic cross-section in the iron tower pedestal;
Fig. 3 is the connection diagram of hydraulic jack system.
The specific embodiment
Referring to figs. 1 through Fig. 3, the charged lift-up device of a kind of high voltage iron tower, it comprises four self-climbing jacking frames 51～54 that can be installed on respectively in the iron tower pedestal, each jacking frame 51～54 is equipped with hydraulic jack 1～4, two hydraulic jack at every intersection diagonal angle are formed the hydraulic jack group by two of sizes respectively, as the jack in the accompanying drawing 31 and 3, jack 2 and 4, wherein big jack 1,2 hydraulic oil delivery outlet 12,22 with little jack 3,4 hydraulic oil input port 31,41 respectively by oil pipe 71,72 are connected, described big, it highly is synchronous that the hydraulic stem 13～43 of little jack 1～4 raises.The course of work of every group of jack group: with jack 1 and 3 is example, when jacking, hydraulic oil injects from the hydraulic oil input port 11 of big jack 1, the hydraulic stem 13 of this big jack is also need be with unnecessary hydraulic oil toward effluxing by the upper cylinder of this jack 1 when up pushing up, these hydraulic oil are from the hydraulic oil input port 31 of hydraulic oil delivery outlet 12 by the little jack 3 of oil pipe 71 injections, the hydraulic stem 33 of little jack 3 is up pushed up, greatly, hydraulic stem 13 when the Capacity design of little jack cylinder makes above-mentioned work and 33 lift remain synchronously, thus stability of tower when having improved control accuracy and construction.
In order to make the balance of iron tower when working better, the utility model also is provided with a centralized hydraulic pressure control device 6, its fuel feed pump 61 is connected in parallel in the hydraulic oil input port 11,21 of two big jack 1,2, when iron tower is applied to wherein pressure on one group of jack and increases, this pressure reaches another group jack by the oil feeding line of parallel connection simultaneously, the pressure of iron tower is evenly born by four jack, thereby made the jacking operation time keep the balance of iron tower as far as possible.
The design's lift-up device does not need transmission line of electricity is had a power failure in work progress because balance is good, thereby has ensured normal production of people and life, has guaranteed that iron tower is in charged jack-up construction process safe yet.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
