Background

Rescue tripod is a rescue facility that extensively is used for well, pipeline or airtight space operation, and this tripod mainly comprises telescopic stabilizer blade, take self-locking function's capstan winch and hoist cable, opens the back with the stabilizer blade and fixes at the well top during the use, then connects hoist cable on operation personnel's safety belt, and the rethread hand cranking winch crank puts down the hoist cable, makes rescue personnel move down. At present, the telescopic and fixing mode of the support leg is to arrange a plurality of positioning holes on the telescopic part and fix the telescopic part by passing a bayonet lock through the positioning holes. In order to facilitate the extraction operation of a user, most of the conventional clamping pins are in an L-shaped structure, one end of each clamping pin penetrates through the positioning hole to play a positioning function, and the other end of each clamping pin is positioned outside the positioning hole and used as a handle for the user to hold. However, due to the fact that the limit function is lacked after the clamping pin structure penetrates into the tripod, the possibility that the clamping pin is pulled out due to external force impact or misoperation exists in the using process of the tripod, and the safety performance of the rescue tripod is reduced. If structures such as a bolt and the like are added on the bayonet lock for limiting, the operation complexity of the bayonet lock is increased, and the normal use of a user is influenced.

On the other hand, in order to facilitate the operation of a user, the winch in the current rescue tripod also needs to have the height adjusting capability; however, the existing lifting fixing structure for the winch easily causes the winch to skid after being fixed or loosen after being collided and mistakenly, so that the safety performance of the rescue tripod is further reduced.

Therefore, the existing rescue tripod with the lifting adjusting function cannot have the characteristics of good safety and convenience in operation at the same time.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A height-adjustable rescue tripod comprises a rescue support 1 consisting of three support legs which are rotatably connected, wherein the top of the rescue support 1 is connected with a downward fixed pulley 2, the fixed pulley 2 is provided with a sling 3, the end part of the sling 3 penetrates through the fixed pulley 2 and is connected with a winch 4 positioned on the support legs, the support legs comprise an upper support leg 5 and a lower support leg 6 which are mutually nested, the top of the lower support leg 6 extends into the upper support leg 5 and is provided with a plurality of parallel adjusting holes 7, and the upper support leg 5 is connected with a clamping pin 8 penetrating through the adjusting holes 7; the winch 4 is detachably connected with an upper support leg 5 through an installation frame, the installation frame comprises a frame body 9 with a U-shaped cross section, one end of the frame body 9 is connected with the winch 4, the other end of the frame body 9 is hinged with a pressing cover 10, the upper support leg 5 is positioned between the frame body 9 and the pressing cover 10, and a positioning assembly is connected between the frame body 9 and the pressing cover 10; bayonet lock 8's appearance is the annular, and bayonet lock 8's left end passes regulation hole 7 and extends to the 5 outsides of supreme stabilizer blade, and bayonet lock 8's right-hand member extends to bayonet lock 8's left end one side from the outside of going up stabilizer blade 5, and 8 left ends of bayonet lock and 8 right-hand members of bayonet lock overlap each other on the horizontal direction, and 8 left ends of bayonet lock and 8 right-hand members of bayonet lock misplace from top to bottom in vertical direction.

The positioning assembly comprises a pin shaft 11 detachably connected with the frame body 9, a stud 12 is rotatably connected to the pin shaft 11, one end of the stud 12 penetrates through the pressing cover 10 and is connected with a fixing nut 13, and a rotating handle is arranged on the fixing nut 13.

The pressing cover 10 is provided with a U-shaped opening 14 for the stud 12 to pass through.

The end part of the stud 12 is sleeved outside the pin shaft 11 through a lantern ring 15, a pushing surface 16 is arranged on the stud 12 on one side of the lantern ring 15, the appearance of the lantern ring 15 is polygonal, a groove body 17 buckled and connected with the lantern ring 15 is arranged on the frame body 9, and a disc spring 18 is arranged between the frame body 9 and the pin shaft 11.

The support body 9 and the pressing cover 10 leave a gap on one side close to the positioning assembly, and the inner sides of the support body 9 and the pressing cover 10 are both provided with flexible rubber pads attached to the upper support legs 5.

The utility model discloses a theory of operation: this application places rescue support 1 in the top of well hole earlier when using, upwards rotates bayonet lock 8 again to 8 right-hand members of bayonet lock and last stabilizer blade 5 dislocation each other, then the level is taken bayonet lock 8 out and is made it and regulation hole 7 alternate segregation to relieve the lock to last stabilizer blade 5 and lower stabilizer blade 6. After the bayonet 8 is pulled out, the telescopic position of the lower support leg 6 is firstly readjusted so as to change the height of the rescue support 1, and then the bayonet 8 is reinserted in the same way to achieve the positioning function. Bayonet lock 8 inserts the back and can rotate to the downward state that hangs down under the action of gravity to make 8 right-hand members of bayonet lock overlap each other with last leg 5 on the level is placed, utilize 8 right-hand members of bayonet lock to carry out horizontal spacing to bayonet lock 8 promptly, make bayonet lock 8 can't directly take out under this angle.

Rescue support 1's high fixed back, the operating personnel is through the back of turning handle unscrewing fixation nut 13 to it is spacing to relieve sticising between mounting bracket and the last stabilizer blade 5, makes the operating personnel can be through the high position of adjustment capstan winch 4 on last stabilizer blade 5, thereby the convenient control to 4 crank of capstan winch. After the winch 4 is in place, the operator screws the fixing nut 13 again and compresses the compression cover 10, so that the mounting frame and the upper supporting leg 5 are compressed again and play a limiting function, and the mounting frame is prevented from loosening.
