The bolt pulling device for the large steel mold comprises a hydraulic oil cylinder and an oil cylinder telescopic rod; the telescopic rod is arranged at one end of the oil cylinder; a hydraulic controller controls the flowing direction of hydraulic oil in the oil cylinder so as to control the telescopic rod to extend out from the oil cylinder or retract into the oil cylinder; the bolt pulling device for the large steel mold is characterized in that a supporting arm is arranged at the extending end of the telescopic rod of the oil cylinder; the supporting arm is supported on a steel mold from which a bolt is pulled; a connector is arranged at the front end of the telescopic rod; the connector is connected with the pulled bolt and is universally connected with the front end of the telescopic rod. The bolt pulling device for the large steel mold is simple in structure and convenient to connect and use; the defects of a manual bolt pulling method are overcome by replacing manpower by a machine by effectively combining actual situations in the field; the labor intensity of workers is lightened; the work efficiency is improved; meanwhile, the time cost is also reduced.
Description
Technical field
The utility model belongs to building implement field, and particularly a kind of large punching block bolt pulls up device.
Background technology
In building operations; when large punching block bolt is extracted; need to bolt be impacted out to a part with manually swinging sledgehammer; manually with iron pestle, whole bolt pestles are gone out afterwards, sledgehammer is pounded in the process of hitting, and the end of bolt is hit blunt; need grinding process; sledgehammer is constantly pounded and is hit, and large punching block can produce deformation, and impact is installed and used.Conventional bolt method for pulling out drops into more than manpower, wastes time and energy.
Summary of the invention
The purpose of this utility model is to propose a kind of large punching block bolt to pull up device, is to be made up of hydraulic jack and hydraulic pump; On hydraulic jack, connect and rotate freely nut and bracing frame.Hydraulic pump enters oil pressure in oil cylinder, and cylinder rod inwardly advances, and rotates freely nut and is screwed on bolt, along with the inside propelling of cylinder rod, drives bolt outwards to extract, time saving and energy saving.
To achieve these goals, the technical solution of the utility model is: a kind of large punching block bolt pulls up device, comprise a hydraulic jack and oil cylinder expansion link, expansion link, in one end of oil cylinder, stretches out and indentation by the flow direction control expansion link of hydraulic oil in hydraulic controller control oil cylinder from oil cylinder; Described oil cylinder is provided with support arm at expansion link external part, and support arm, for being supported on the punching block that is pulled out bolt, is provided with connector at the front end of described expansion link, and connector is connected for pulling out bolt with quilt, and described connector is universal connection with expansion link front end.
Scheme is further: described support arm is made up of at least three support bars and pallet, and pallet is connected to support bar one end, and the support bar other end is fixed on the cylinder body of oil cylinder.
Scheme is further: on described connector, be provided with nut button silk, nut button silk for pulled out bolt and be connected.
Scheme is further: on described connector, be provided with the pulling claw with crotch, pulling claw for pulled out bolt and be connected, pulling claw and connector are hinged.
Scheme is further: the front end of described expansion link is a bulb, described connector has an inner chamber corresponding with bulb shape, and expansion link front end bulb is placed in the connector inner chamber corresponding with bulb shape and realizes connector and be connected with the universal of connecting rod front end.
The beneficial effects of the utility model are: the utility model is simple in structure, connect easy to usely, effectively replace artificial solution manually to pull out the deficiency of bolt method in conjunction with on-site actual situations utilization machinery, alleviated workman's labour intensity, improve operating efficiency, also saved time cost simultaneously.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation with crotch pulling claw.
Detailed description of the invention
A kind of large punching block bolt pulls up device, as depicted in figs. 1 and 2, described device comprises a hydraulic jack 1 and oil cylinder expansion link 2, and expansion link is in one end of oil cylinder, and the flow direction control expansion link of controlling hydraulic oil in oil cylinder by hydraulic controller 3 stretches out and indentation from oil cylinder; Described oil cylinder is provided with support arm 4 at expansion link external part, support arm is for being supported on the punching block 6 that is pulled out bolt 5, be provided with connector 7 at the front end of described expansion link, connector is connected for pulling out bolt with quilt, and described connector is universal connection with expansion link front end.
In embodiment: as shown in Figure 1, described support arm is made up of at least three support bar 4-1 and pallet 4-2, and pallet is connected to support bar one end, and the support bar other end is fixed on the cylinder body of oil cylinder.
In embodiment: as shown in Figure 1, be provided with nut button silk 7-1 on described connector, nut button silk is connected for pulling out bolt with quilt.
In embodiment: as shown in Figure 2, be provided with the pulling claw 7-2 with crotch on described connector, pulling claw is connected for pulling out bolt with quilt, and pulling claw and connector are hinged.
In embodiment: the described universal various structures that is connected with; In the present embodiment, as depicted in figs. 1 and 2, the front end of described expansion link is a bulb, and described connector has an inner chamber corresponding with bulb shape, and expansion link front end bulb is placed in the connector inner chamber corresponding with bulb shape and realizes connector and be connected with the universal of connecting rod front end.
Cost accounting compared with pulling up as the large punching block bolt of the present embodiment and traditional approach is:
Material cost: adopt sledgehammer to pound out bolt, part bolt one cephalic par need to carry out grinding process, it is 2.5 yuan that the polishing of bolt needs comprehensive cost, and in bolt, every 3 the insides have 1 needs to carry out grinding process, and sharing each bolt equally, to need comprehensive cost be 0.83 yuan; Part bolt one cephalic par impacts in process and becomes curved, need to carry out straightening processing, and in bolt, every 8 the insides have 1 needs to carry out straightening processing, and sharing each bolt equally, to need comprehensive cost be 0.2 yuan.
Human cost: according to the per day wage of workman and the per day bolt quantity of extracting of workman, estimate and extract each 2.0 yuan of bolt needs.
(2) use the present embodiment device
Material cost: the present embodiment device is made needs 610 yuan/, can extract 100,000 bolts, shares 0.06 yuan of each bolt needs.Human cost: according to the per day wage of workman and the per day bolt quantity of extracting of workman, estimate and extract 0.2 yuan/of bolt needs.To sum up: extract in through-wall bolt process, use the present embodiment device can save 2.8 yuan/.
