Description
Technical field
The utility model relates to a kind of drawbench, specifically, is a kind of split bolt extracting device.
Background technology
The reinforced concrete structure of industrial premises, Equipment Foundations props up in moulding and can adopt a large amount of Ф 12 or the split bolt of Ф 14 to carry out fixed form in the mold process, for the turnover that realizes split bolt is used, split bolt outside cover diameter in structure is greater than the PVC plastic tube of 3～5mm, so that having torn template behind the concrete formation open helps extracting shank of bolt and utilizes, but often because shank of bolt is subjected to the caused micro-strain of external force in the work progress after installation or split bolt is longer, manually can't extract, and the drawing effect is low, loses more than gain.
Therefore the known shank of bolt apparatus of extracting exists above-mentioned all inconvenience and problem.
Summary of the invention
The purpose of this utility model, it is extensive to be to propose a kind of use, to the harmless split bolt extracting device of xoncrete structure outward appearance.
For achieving the above object, technical solution of the present utility model is:
A kind of split bolt extracting device comprises a base (8), two jack (7), and a power transmission shoulder pole (5), a bolt branch sleeve (6) and a wedge bolt jig is characterized in that:
Described base (8) is one to be provided with the iron plate of a hole in the center;
Described two jack (7) are arranged on the described base (8), and are arranged on the both sides of described base (8) hole symmetrically;
Described power transmission shoulder pole (5) is one to be provided with the square steel of a hole (2) in the center, is arranged on the top of described two jack (7) movably;
Described wedge bolt jig (3) is arranged on the top of described power transmission shoulder pole (5) movably;
One end of described bolt branch sleeve (6) can connect need open the bolt that pulls out, and the other end connects a pair of screw rod (1) that draws.
Split bolt extracting device of the present utility model can also be further achieved by the following technical measures.
Aforesaid extracting device, it in the wherein said wedge bolt jig (3) the wedge shape cylinder of two described Screw arbor with nut at both-ends of obvolvent (1), described wedge shape cylinder is outward for waling the annulus hoop of described two wedge shape ground tackles, between described annulus hoop and the wedge shape ground tackle with the screw thread fastening described Screw arbor with nut at both-ends (1) jointly that is connected as a single entity.
Aforesaid extracting device is provided with stiffener (4) in the square steel of wherein said power transmission shoulder pole (5).
After adopting technique scheme, split bolt extracting device of the present utility model has the following advantages:
Simple and safe operation, light and handy, speed is fast, effect is high.
2. solve split bolt nonrecoverable problem in a mold process, realized that repeatedly turnover is used, saved construction cost, increased work efficiency, saved the duration.
Description of drawings
Fig. 1 is an embodiment schematic diagram of the utility model split bolt extracting device.
Among the figure: 1 is Screw arbor with nut at both-ends, and 2 is hole, and 3 is the wedge bolt jig, and 4 is stiffener, and 5 are the power transmission shoulder pole, and 6 is the bolt branch sleeve, and 7 is jack, and 8 is base; Arrow is represented the direction of power among the figure.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is illustrated further.
Now see also Fig. 1, Fig. 1 is an embodiment schematic diagram of the utility model split bolt extracting device.As shown in the figure, the base (8) that described 2 RC-59 types separation hydraulic jacks (7) are fixed on 5x100x300mm connects on the steel plate, and connected mode adopts 3 means of spot welds, weld seam effective depth h
fBe not less than 5mm, the circular hole of a 30mm is opened in the connecting plate middle part, passes the hole so that the required split bolt of extracting is reserved.
2 hand-hydraulic jack (7) are taked hand-operated valve is cascaded with connecting rod, weld out a handlebar in the middle of the connecting rod, realize that the upper and lower handlebar that presses starts 2 jacking oil pumps synchronously outside pushing tow of fuel feeding simultaneously, and the length of a stroke is 230mm.
One end of described bolt branch sleeve (6) can connect need open the bolt that pulls out, and the other end connects a pair of screw rod (1) that draws
The transmission of the power of split bolt extracting device is to form the split bolt withdrawal force by power transmission shoulder pole pushing tow bolt jig, the square steel of the 100x100mm that power transmission shoulder pole (5) employing 5mm steel plate is made, the hole (2) of opening Ф 25mm in the middle part is so that the usefulness of required split bolt reservation of extracting.Wedge bolt jig (3) adopts two taper buckles to embrace on split bolt (1), its periphery is a circular, hoop, be enclosed within the periphery of two taper jigs, form jack top power transmission shoulder pole, the power transmission shoulder pole passes to power on two taper buckles again, because of being taper, one big one little, make a part of power of outwards pulling change into the power of chucking Screw arbor with nut at both-ends, thereby realize bolt is extracted smoothly.
The operating procedure of the utility model split bolt extracting device is as follows:
Possessing by the structure of extracting the bolt condition, utilize traveling centering, set up job platform, after the split bolt head that needs are extracted is cleared up, one end of bolt branch sleeve connects the split bolt head that need extract, the other end of bolt branch sleeve connects the lengthening Screw arbor with nut at both-ends with diameter, the jack base circular hole of extracting device is through on the required reinforcing bar of extracting, lever is dialled to the right, jack is set back, after again the power transmission shoulder pole being enclosed within on the required split bolt of extracting, two taper buckles being installed being tightened circular outer hoop afterwards.Beginning is pressed the press operation handle earlier gently, and the power transmission faying face is in contact with one another firmly, and especially the bolt enclasp device can not become flexible, and after each parts synchronous working gets the hang of, strengthens the application of force of lever again, accelerates the speed of pulling.
When pulling to the range of jack, with the jack oil return, repeat above-mentioned steps, a sectionly outwards extract, until all extracting whole split bolt.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique under the situation that does not break away from spirit and scope of the present utility model, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
