Description
Technical field
The utility model relates to the flange dismounting, relates in particular to a kind of flange separator.
Background technology
In pipeline maintenance construction, pipe flange connection device (like valve, flowmeter etc.) and pipe flange clamping connection tension often take place, or because the flange connect hours is longer, pipe flange becomes rusty extremely together, is difficult to the situation of removing from pipeline.The general now construction method that adopts is to insert the adpting flange slit with crow bar, prizes by force with manpower to enlarge the gap, and flange is separated, and is prone to hit, dodge the danger of bumping the workmen when using crow bar; Use crow bar to receive field operation space (like eminence, narrow position) restricted influence, speed is slow.And the large scale flange big for volume, that weight is big dismounting also needs prize simultaneously with several manpowers, and not only labour intensity is big, and safety inadequately.Also can adopt oxygen welding cutting means, but to the explosive pipeline that waits dangerous material of process of conveying inflammable is arranged, like gas piping, the fire operation danger coefficient is very high, and accidents such as gas poisoning, blast take place easily.
China's utility model patent 200720032726.9 discloses a kind of flange separator of pipe flange fast assembling-disassembling; It has an oil cylinder; Taper is installed in the end of oil cylinder separates head; With the bolt hole of flange location, the taper cutting edge of separator is inserted in the middle of two flanges that will separate the flange separation that the thrust of utilizing oil cylinder to produce will become rusty dead.This flange separator complex structure, manufacturing cost height; And inconvenient fixing on flange, practicality is not high.
The utility model content
The utility model technical problem to be solved provides a kind of simple in structure, and fixing reliable, the flange separator that applicability is high overcomes the above-mentioned technical problem that exists in the prior art.
The utility model adopts following technical scheme:
A kind of flange separator of the utility model; Comprise hydraulic jack, wedge shape top and bracing frame, a fixing base on the said hydraulic jack, said base middle part is provided with through hole; Said wedge shape top is passed through hole and is connected with the piston rod of said hydraulic jack; Said base two ends are supported on respectively on two support frames as described above, and sliding on each bracing frame is provided with two supporting legs, wears a screw rod between said two supporting legs.
Further, support frame as described above comprises two gripper shoes that are parallel to each other, and a chute is respectively established in said supporting leg both sides, and supporting leg is fastened on the said gripper shoe through chute.
Further, establish an I-steel on the support frame as described above, a bayonet socket is respectively established at said base two ends, and said I-steel is folded in the said bayonet socket.
Further, bolt hole is established in said supporting leg lower end, and said bolt hole is a mounting hole, and said screw rod is located in the bolt hole.
Further, said wedge shape top and piston rod screwed connection.
Through above technical scheme, the utlity model has following technique effect:
The utility model can separate the large-scale pipeline flange quickly and easily, and convenient maintenance and the maintenance of accomplishing pipeline increased work efficiency, and the harm of having avoided fire operation to bring has guaranteed workmen's safe construction, and it is dangerous to greatly reduce construction.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model side view;
Fig. 3 is the utility model vertical view.
The specific embodiment
Combine accompanying drawing that the utility model flange separator is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
Like Fig. 1 and shown in Figure 2, a kind of flange separator of the utility model comprises hydraulic jack 1, wedge shape top 2 and bracing frame; A fixing base 6 on the hydraulic jack; The base middle part is provided with through hole, and wedge shape top 2 is passed through hole and is connected with the piston rod of hydraulic jack, and the base two ends are supported on respectively on two above-mentioned bracing frames; Slide to be provided with between 3, two supporting legs of two supporting legs on each bracing frame and wear a screw rod 4.After this device assembling completion, can fix this device through screw rod 4 is located in the flange hole on the pipeline, and then insert in the middle slit of flange, thereby flange is separated through the motion promotion wedge shape top 2 of hydraulic cylinder piston rod.
Like Fig. 1, Fig. 2 and shown in Figure 3, each bracing frame of present embodiment comprises that 5, two supporting legs 3 of two gripper shoes that are parallel to each other are slidingly arranged in 5 of two gripper shoes, and bolt hole 31 is established in the supporting leg lower end, and screw rod 4 is located in the bolt hole 31.A bracing frame is respectively placed in the flanged pipe both sides, through screw rod 4 is fixed in the flange hole on the pipeline and can bracing frame be fixed.Because of the pipeline construction circumstance complication, a chute is respectively established in the supporting leg both sides, and supporting leg 3 is fastened on the gripper shoe 5 through chute, and the setting of chute can be slided supporting leg 3 along gripper shoe 5, and this device can be adjusted according to the practice of construction environment.Simultaneously because pipeline is long neglected and in disrepair or flange is diversified in specifications; Possibly there is deviation in flange hole apart from the position at edge; The flange hole physical location of both sides maybe be asymmetric; Therefore bolt hole 31 is designed to mounting hole, and screw rod 4 can have the adjustment up and down of certain amplitude in mounting hole, make this device scope of application wider.
Establish an I-steel 7 on the bracing frame, a bayonet socket 61 is respectively established at the base two ends, and I-steel 7 is folded in the bayonet socket 61.I-steel can directly be weldingly fixed on the gripper shoe 5, as is inconvenient to weld, and also can establish several metal derbies in the I-steel bottom, and metal derby is folded between two gripper shoes and through bolt, can makes things convenient for the flexible dismounting between I-steel and bracing frame like this.Setting through I-steel makes the base two end supports on two bracing frames, is not limited to I-steel here and fixes, and selects suitable manner that base support will be got final product on bracing frame according to base shape, structure.
After the installation of this device, when using this device, at first choose the wedge shape top 2 of appropriate size, with the piston rod screwed connection in wedge shape top 2 and the hydraulic jack according to the flanged pipe size; Remove the bolt in the pipe flange hole then, screw rod 4 is located in fixing this device in the flange hole; Rotary screw 4 these setting positions of adjustment make wedge shape push up the middle slit of 2 align with tube flanges; Primer fluid compressing cylinder 1, piston rod drive gap and the propelling that pipe flange is inserted on wedge shape top 2, thus parting flange.
This device can conveniently separate the large-scale pipeline flange, and can change the wedge shape top of different size according to the flange actual size, and the pipeline that separates various media, specification connects.
More than a kind of flange separator that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
