Abstract
The invention belongs to the technical field of fasteners, and provides a tool for assisting in drawing out an expansion bolt. The problem that the work efficiency of drawing out the expansion bolt is low is solved. The tool comprises a screw rod, at least two hooks are arranged on the lower portion of the screw rod, each hook comprises a hook rod and a hook end, the hook rods are connected with the lower portion of the screw rod, the axes of the hook rods are parallel to the axis of the screw rod, the hook ends are in the direction away from the axis of the screw rod, and the hooks are elastic. The upper portion of the screw rod is sleeved with a nut. The tool improves the work efficiency of drawing out the expansion bolt.
Description
Technical field
The invention belongs to the technical field of securing member, being specifically related to a kind of for drawing the instrument getting expansion bolt.
Background technology
In the job site of nuclear power station, have the situation of Change In Design, after Change In Design, just needs are removed the support of installation and are reorientated installation, and support bracket fastened expansion bolt also needs to draw from body of wall or substrate to take out simultaneously.Draw when getting expansion bolt, the screw rod of expansion bolt and expansion first class sections ratio are easier to draw to be got, and use conventional method just can draw and take out, and the expansion joint of expansion bolt is stuck in body of wall or substrate, be difficult to take out from body of wall or substrate, cause the work of getting of drawing of expansion bolt to be required great effort very much.At present, draw when getting expansion bolt, expansion joint clamped by the instruments such as operating personnel's pliers, is then firmly pulled outwardly.Because expansion joint is stuck in body of wall or substrate, fixing is very firm, so normally expansion joint can not be pulled out by very large strength, wastes a large amount of manpower and materials.Current expansion bolt to draw the work of getting very inconvenient, operating efficiency is lower.
Summary of the invention
Get the lower problem of operating efficiency to solve drawing of expansion bolt, the present invention proposes a kind ofly to draw the instrument getting expansion bolt, to improve the efficiency drawing the work of getting expansion bolt for auxiliary.
Of the present inventionly comprise screw rod for drawing the instrument getting expansion bolt, this screw rod bottom is provided with at least two hooks, this hook comprises shank and hook end, described shank is connected with the bottom of described screw rod, the axis of described shank and the axis being parallel of described screw rod, described hook end is towards the direction of the axis away from described screw rod, and described hook has elasticity; The top of described screw rod is arranged with nut.
Wherein, the top of described screw rod is provided with handle, and this handle is positioned at above described nut.
Wherein, described hook is two, and is symmetrical arranged on described screw rod.
Wherein, described hook is made up of elastic steel bar.
Wherein, pad is provided with below described nut.
Of the present invention have following beneficial effect for drawing the instrument getting expansion bolt:
1. draw in the process of getting at expansion bolt, the screw rod of expansion bolt and expansion first class sections are all got than being easier to draw, and use conventional method just can draw and take out, and expansion joint is stuck in body of wall or substrate, be difficult to draw from body of wall or substrate take out, draw when getting and also require great effort most; Instrument of the present invention make expansion joint to draw the work of getting more laborsaving, thus make expansion bolt draw that work of getting becomes simply laborsaving.When using instrument of the present invention, only need operating personnel's rotating nut, with the larger pulling force giving screw rod one outside, the hook of screw rod bottom hangs on expansion joint, thus the pulling force giving expansion joint one outside, continuous rotating nut, to pull out expansion joint from body of wall or substrate.The power of rotating nut is less, but the pulling force making screw rod outside produced is comparatively large, and such operating personnel only use less power, just can produce larger power to be pulled out from body of wall or substrate by expansion joint.Instrument of the present invention make expansion bolt to draw the work of getting more laborsaving simpler, draw to get the time that expansion bolt consumes and shorten, improve the efficiency drawing the work of getting expansion bolt, and draw when getting expansion bolt and only need operating personnel, save manpower.
2. instrument of the present invention is easy to learn, easy left-hand seat, flexible to operation, and compact, easy to carry, can use in narrow and small operating environment.
3. each part of instrument of the present invention is all common parts that job site often uses, and when making instrument of the present invention, can gather materials on the spot, and makes the cost of manufacture of instrument of the present invention very low like this.
Accompanying drawing explanation
Fig. 1 is the schematic front view for drawing the instrument getting expansion bolt of the present invention;
Fig. 2 is the using state figure for drawing the instrument getting expansion bolt of the present invention.
Detailed description of the invention
Instrument of the present invention is introduced below in conjunction with Fig. 1 and Fig. 2.
As shown in Figure 1, of the present inventionly comprise screw rod 10 for drawing the instrument getting expansion bolt, the bottom of screw rod 10 is symmetrically arranged with two hooks 11, and hook 11 comprises shank 111 and hook end 112, shank 111 is fixed on the bottom of screw rod 10, the axis of shank 111 and the axis being parallel of screw rod 10; Hook end 112 is towards the direction of the axis away from screw rod 10; Hook 11 has elasticity, and being made up of elastomeric material, such as, can be made up of elastic steel bar.The top of screw rod 10 is arranged with nut 12 and pad 13, and pad 13 is positioned at the below of nut 12.The top of screw rod 10 is also provided with handle 15, and handle 15 is positioned at the top of nut 12.
As shown in Figure 2, the using method of instrument of the present invention, the first step, screws out from the expansion joint 16 of expansion bolt by the screw rod of expansion bolt; Second step, stretches into instrument of the present invention in expansion joint 16, when hook 11 passes the opening part bottom expansion joint 16, there is flexible hook 11 to strut to both sides, thus tangle expansion joint 16, wherein, two hooks 11 are symmetrical arranged on screw rod 10, link up with 11 like this and more easily tangle expansion joint 16; 3rd step, rotating nut 12, operating personnel rotate along with nut 12 to prevent screw rod 10 with hand steered handle 15, make nut 12 prop up body of wall 14; 4th step, operating personnel continue rotating nut 12, and rotate along with nut 12 to prevent screw rod 10 with hand steered handle 12, so continuous rotating nut 12, be equivalent to pulling force outside to screw rod 10 1 under the support of body of wall 14, thus the pulling force giving expansion joint 16 1 outside, expansion joint 16 is pulled out from body of wall 14.
