Abstract
The utility model discloses a telescopic unhooking preventing device which comprises a first steel pipe and a second steel pipe. The outer diameter of the first steel pipe is matched with the inner diameter of the second steel pipe, the first steel pipe is inserted with the second steel pipe in a sliding mode, more than two fixing holes are evenly distributed in the first steel pipe in the length direction of the first steel pipe, a screw hole is formed in the end portion, inserted with the first steel pipe, of the second steel pipe, a screw cap is welded on the second steel pipe on the screw hole, the screw cap and the screw hole are in screw joint with a bolt, and the bolt penetrates through the screw hole and penetrates in any fixing hole. The free end of the first steel pipe is connected with a first cast-off preventing hook, and the free end of the second steel pipe is connected with a second cast-off preventing hook. The original situation that people and a car form a whole is avoided, even though a rollover accident occurs to a crank arm car, operating personnel can only be hung in the air by the telescopic unhooking preventing device, and cannot fall down along with the rollover of the crank arm car, operation safety factors are greatly increased, the good function of a protective umbrella is achieved, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of cigarette factory throwing shop safety protective device.
Background technology
What taked in the throwing workshop is grid structure, and rack is highly overhead 8.5 meters, and the advancing of air-conditioning duct, return air inlet are installed on rack.Normal produce the advancing of air-conditioning duct after a period of time, the return air inlet blading deposit is more, need to clean, and the curved arm vehicle adjustable height deficiency that the throwing workshop is used, safety strap is local without hanging, the operating personnel can only be suspended on safety strap on the curved arm vehicle guardrail, and namely people and car become one during cleaning operation.Because aspect ratio is higher, during operation, curved arm vehicle is in the state of rocking, and this has just increased the weight of operating personnel's feared state of mind, and more seriously in a single day hydraulic fault or other accident appear in curved arm vehicle, when rollover occurred, the people just will certainly turn on one's side with car, form potential safety hazard.
The utility model content
The purpose of this utility model is to provide a kind of Telescopic anti-drop hook device that can eliminate the potential safety hazard of curved arm vehicle rollover formation.
For achieving the above object, Telescopic anti-drop hook device of the present utility model comprises the first steel pipe and the second steel pipe, the internal diameter of the external diameter of the first steel pipe and the second steel pipe is suitable, and the first steel pipe and the second steel pipe sliding plug are together, on the first steel pipe, be evenly equipped with along its length plural fixed orifice, the end of the end that the second steel pipe and the first steel pipe plug is provided with a hole, on second steel pipe at place, silk hole, be welded with nut, nut and silk hole are bolted with bolt, and bolt penetrates arbitrary fixed orifice after passing described silk hole; The free end of the first steel pipe is connected with the first anti-knocking over hook, and the free end of the second steel pipe is connected with the second anti-knocking over hook.
Described fixed orifice is evenly distributed with 3-5 along the length direction of the first steel pipe.
Between the described first and second anti-knocking over hooks, be provided with connection cord.
The aperture of described fixed orifice is 10.5 millimeters.
Advancing of the air-conditioning duct of installing on the rack of throwing workshop, when the blade at return air inlet place need to clean, the operating personnel can hang over the anti-knocking over hook of the utility model one end workshop safety top failure-free local (as the steel grating at top, workshop) securely, then the other end of the present utility model is connected with the safety strap of self, so just avoided people and car in the past to form the situation of integral body, even if curved arm vehicle generation rollover accident, the operating personnel also only can be suspended in the air by Telescopic anti-drop hook device of the present utility model, and can not fall with the rollover of curved arm vehicle, greatly increased the job safety coefficient, played the effect of good umbrella, the staff can be worked more securely, improved work efficiency.
When the length required when workplace is different, can back out bolt, the first steel pipe, to after stretching into one section suitable distance in the second steel pipe, then is aimed at described nut on the first steel pipe to corresponding fixed orifice and is screwed into bolt, thereby the utility model is adjusted to applicable length.
Fixed orifice is evenly distributed with 3-5 along the length direction of the first steel pipe, can adapt to the requirement of most of workplaces to collapsing length.Connection cord the utility model easy to use is set.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model while extending to extreme length;
Fig. 2 is the birds-eye view that in Fig. 1, the first steel pipe and first is prevented the knocking over hook;
Fig. 3 is the structural representation of the utility model while being contracted to minimum length.
The specific embodiment
As shown in Figure 1 to Figure 3, Telescopic anti-drop hook device of the present utility model comprises the first steel pipe 1 and the second steel pipe 2, the internal diameter of the external diameter of the first steel pipe 1 and the second steel pipe 2 is suitable, and the first steel pipe 1 and the second steel pipe 2 sliding plugs are together, on the first steel pipe 1, be evenly equipped with along its length plural fixed orifice 3, the end of the end that the second steel pipe 2 and the first steel pipe 1 plug is provided with a hole, and (the silk hole is common technology, figure does not show), on second steel pipe 2 at place, silk hole, be welded with nut 4, the internal diameter in nut 4 and silk hole is 10 millimeters and the two and is bolted with bolt 5, this bolt 5 preferably adopts annular knurl, to facilitate adjusting.Bolt 5 penetrates arbitrary fixed orifice 3 after passing described silk hole, thereby the first and second steel pipes 2 are linked together securely, prevents the two telescopic movable.
The free end that the free end of the first steel pipe 1 is connected with the first anti-knocking over hook 6, the second steel pipes 2 is connected with the second anti-knocking over hook 7.
Described fixed orifice 3 is evenly distributed with 3-5 along the length direction of the first steel pipe 1.Between the described first and second anti-knocking over hooks 7, be provided with connection cord.The aperture of described fixed orifice 3 is 10.5 millimeters.Described the first and second steel pipes 2 all preferably adopt 6 minutes galvanized pipes, and bolt 5 adopts stainless steel material, the utility model is conducted oneself with dignity lighter in the weight that can bear more than 120 kg.
Advancing of the air-conditioning duct of installing on the rack of throwing workshop, when the blade at return air inlet place need to clean, the operating personnel can hang over workshop safety top failure-free local (as the steel grating at top, workshop) securely by the of the present utility model first anti-knocking over hook 6, then the second anti-knocking over hook 7 of the utility model other end is connected with the safety strap of self, so just avoided people and car in the past to form the situation of integral body, even if curved arm vehicle generation rollover accident, the operating personnel also only can be suspended in the air by Telescopic anti-drop hook device of the present utility model, and can not fall with the rollover of curved arm vehicle, greatly increased the job safety coefficient, played the effect of good umbrella, the staff can be worked more securely, improved work efficiency.When the length required when workplace is different, can back out bolt 5, the first steel pipe 1, to after stretching into one section suitable distance in the second steel pipe 2, then is aimed at described nut 4 on the first steel pipes 1 to corresponding fixed orifice 3 and is screwed into bolt 5, thereby the utility model is adjusted to applicable length.
