Abstract
An adjustable manhole safety isolation lock is applied to petrochemical containers and pipeline flange type manholes. One end of each hook-shaped steel plate is provided with a hook, 4-20 through holes are distributed at the other end of each hook-shaped steel plate along the central line, and the other end of each two hook-shaped steel plates is connected between the upper positioning plate and the lower positioning plate; the fixing bolt penetrates through the through hole of the upper positioning plate, the through hole of the hook-shaped steel plate and the through hole of the lower positioning plate to fix the hook-shaped steel plate, the upper positioning plate and the lower positioning plate together. Through holes are respectively arranged on the upper positioning plate and the lower positioning plate and are arranged in a radial mode, and the distance between every two adjacent through holes on the upper positioning plate and the lower positioning plate is the same as the distance between every two adjacent through holes on the hook-shaped steel plate. When the adjustable hole hook-shaped steel plate is used on a manhole or a pipeline, the proper number and the proper length of the adjustable hole hook-shaped steel plates are selected according to the size of an opened manhole, so that the personnel in the segmented maximum space can not pass through the adjustable hole hook-shaped steel plate, and the effect of limiting the personnel to enter the limited space is achieved.

The technical solution adopted in the utility model is: adjustable manhole is isolated safely lockset, comprise that hook-type steel plate, upper positioning disk, lower positioning disk, set bolt and screw form, it is characterized in that: hook-type steel plate is the rectangle steel plate, one end of hook-type steel plate has a hook that is become by Plate Welding, hook can block the edge of manhole flange, and in hook one side of hook-type steel plate a screw hole is arranged, and a screw is arranged in screw hole, tighten the edge that screw can be fixed on hook-type steel plate manhole flange.The other end at hook-type steel plate is evenly distributed with 4～20 through holes along center line.The quantity of hook-type steel plate is 2～36; Per two hook-type steel plate other end center lines are on the same straight line, and per two hook-type steel plate other ends are connected between positioning disk and the lower positioning disk; Three through holes that per two hook-type steel plates are adjacent are relative with the through hole of upper positioning disk and lower positioning disk; Set bolt passes the through hole of positioning disk through hole, hook-type steel plate and the through hole of lower positioning disk, and hook-type steel plate and upper positioning disk and lower positioning disk are fixed together.Described upper positioning disk and lower positioning disk are disc, on upper positioning disk and lower positioning disk, through hole is arranged respectively, through hole is radial arrangement, and the distance between adjacent two through holes on the distance on upper positioning disk and the lower positioning disk between adjacent two through hole and the hook-type steel plate is identical.
Described hook-type steel plate has four, and wherein the other end of two hook-type steel plates is overlapping, and three adjacent through holes form transverse slat relatively; The other end of other two hook-type steel plates is overlapping, and three adjacent through holes form riser relatively; Transverse slat is mutually vertical with riser; Upper positioning disk and lower positioning disk are disc, on upper positioning disk and lower positioning disk, five through holes are arranged respectively, one of them central through hole is in the center, the center line of other four through holes is square arrangement, and the center line of four through holes communicates to the distance of central through hole, and the through hole distance between adjacent two through holes of the center line of four through holes on the distance of central through hole and the hook-type steel plate is identical; Upper positioning disk is on the top of transverse slat or riser, and lower positioning disk is in the bottom of transverse slat or riser, and five set bolts pass respectively the through hole of positioning disk, transverse slat, riser and lower positioning disk, are fixed with nut at set bolt.
For upper positioning disk and lower positioning disk can be locked together, be respectively equipped with lockhole at the relative position of upper positioning disk and lower positioning disk.Can pin with lockset.The quantity of lockhole is 1～6.
The beneficial effects of the utility model: the adjustable manhole of the utility model is isolated safely lockset, at the manhole of opening, when pipeline uses, energy adjustment hole hook-type steel plate can be according to the size of opening manhole, select suitable quantity and regulate suitable length, the maximum space personnel of cutting apart can't be passed through, therefore not only played warning function, also play the restriction personnel and entered the restricted clearance operation effectiveness, the utility model is made by steel plate in addition, with low cost, adopt bolt and general lockset to lock, install with disassemble very convenient.Be convenient to dismounting, a kind of adjustable manhole with low cost is isolated safely lockset.
Description of drawings
Fig. 1 is that the adjustable manhole of the utility model is isolated safely the lock structure generalized section.
Fig. 2 is the sectional drawing of Fig. 1.
Among the figure, 1 hook-type steel plate, the upper positioning disk of 2-, positioning disk under the 3-, 4-set bolt, 5-screw, 6-lockhole.
The specific embodiment
Embodiment 1: be applicable to diameter take one and isolate safely lockset as example as the adjustable manhole of the manhole of 500mm, the utility model is described in further detail.
Consult Fig. 1.The adjustable manhole of the utility model is isolated safely lockset, comprises that four hook-type steel plates 1, a upper positioning disk 2, a lower positioning disk 3, five set bolts 4 and four screws 5 form.Hook-type steel plate 1 is the rectangle steel plate, and length is 350mm, width 50mm, thickness 5mm.One end of hook-type steel plate 1 has a hook that is become by Plate Welding, and the screw hole of a M16 is arranged in hook one side of hook-type steel plate 1, and the screw 5 of a M16 is arranged in screw hole, is evenly distributed with nine through holes at the other end of hook-type steel plate 1 along center line.Per two hook-type steel plates, 1 other end center line is on the same straight line.
