Abstract

The invention provides a handheld type double-foot screw-lifting hole cover lifting device, and relates to a hole cover lifting device. The handheld type double-foot screw-lifting hole cover lifting device aims at solving the problems that because an existing product hole cover needs to be lifted out by multiple workers together, the labor intensity of workers is increased, the lifting time of 10 minutes to 20 minutes is required, and manpower and time resources are wasted. A through hole is formed in the middle of an upper beam. Two lifting feet are installed at the left end and the right end of the upper beam. A lifting hole is formed in the lower end of each lifting foot. A slide sleeve is fixedly installed at the upper end of the upper beam and located over the through hole. The upper end of a slide column is riveted to a supporting frame. The lower end of the slide column penetrates the slide sleeve and the through hole in a slidable manner. The slide sleeve and the slide column are sleeved with a spring. The upper portion of the spring is connected to the supporting frame. The handheld type double-foot screw-lifting hole cover lifting device is used for hole cover lifting.

Description

The port lid of a kind of hand held both feet lifting screw promotes device

Technical field

The present invention relates to a kind of port lid and promote device, the port lid being specifically related to a kind of hand held both feet lifting screw promotes device.

Background technology

Certain product is installed above three port lids, and three port lid geomeries are identical, and this product needs detection every year when storage Once, being also required to before use detect once, detection is required for unloading three port lids, because three port lids are arranged on every time In counterbore, and fix with two screws, in order to enable port lid screw to propose from the counterbore of fixing body, port lid is installed The hole of screw is not designed to unthreaded hole, but is together designed to screwed hole, when the screw of fixing port lid is from peace with the parent installed Dress parent screw in screw out after, it is impossible to from the screw of port lid extract out, so when lifting screw outward, port lid also with From fixing body take out.Because port lid is arranged in counterbore, even if screw unclamps, port lid can not take out from counterbore, The local, one end using special special construction screw, i.e. head of screw for these three port lids is threaded, and another part is little In the polished rod of diameter of thread, after screw screws out from fixing body screw, it is impossible to extract out from the screw of port lid, but need many Individual workman makes a concerted effort to lift out by port lid, not only adds the labor intensity of workman, and when needing the promotion of 10-20 minute Between, waste of manpower and time resource.

Summary of the invention

The invention aims to solve existing product port lid needs multiple workmans to make a concerted effort to lift out by port lid, not only increases Add the labor intensity of workman, and need the promotion time of 10-20 minute, the problem that there is waste of manpower and time resource. And then provide the port lid of a kind of hand held both feet lifting screw to promote device.

The technical scheme is that the port lid of a kind of hand held both feet lifting screw promotes device to include both feet promotion hook, support Frame, spring, sliding sleeve and traveller, both feet promotion hook includes entablature and two promotion feet, and the middle part of entablature offers one Through hole, promotes the two ends, left and right that foot is separately mounted to entablature for two, and two lower ends promoting foot offers a promotion respectively Hole, sliding sleeve is fixedly mounted on the upper end of entablature, and sliding sleeve is positioned at the surface of through hole, and the upper end of traveller is riveted on bracing frame On, the lower end of traveller can be slid through sliding sleeve and through hole, and spring housing is contained on sliding sleeve and traveller, and the top of spring is connected to On bracing frame.

Foot is promoted to include respectively on top tie plate, bottom lifting plate and connecting rod, top tie plate and bottom lifting plate for two Under be arranged in parallel, one end of top tie plate and bottom lifting plate one end connected by connecting rod.

Promote hole to be opened in connecting rod, and promotion hole is that U-shaped promotes hole.

U-shaped promotes the width at the U-shaped mouth in hole to be 5.5-6.5mm.

Bracing frame is " door " shaped support frame.

The present invention compared with prior art has the effect that

The present invention, it can be avoided that tilt jam under the port lid that lifted not vacuum environment during lifting, makes the port lid face of cylinder The most parallel counterbore periphery；Without counterbore down in the case of, it is possible to by the port lid that is assemblied in counterbore quickly from counterbore In take out from bottom to top, than do not promote device work efficiency improve 5 times.

Present configuration is simple, it is simple to manufacture, with low cost.
