The conventional material bag is 0.5t-1t in weight after being filled with, and the material bag can completely bear the corresponding weight of raw and other materials, but scraping and colliding phenomena may occur in the raw and other materials bagging transportation and hoisting processes, so that the material bag is damaged and broken, some of the broken materials cannot be checked out through manual work, so that an operator can untie the rope belt below the material bag, the broken material bag is broken, the falling risk occurs, and the potential safety hazard is realized.
SUMMERY OF THE UTILITY MODEL
Aiming at the existing problems, the utility model provides the telescopic frame for preventing the feeding from falling and damaging, which can prevent the bag from falling and damaging people and protect the life safety of operators.
The utility model adopts the following technical scheme:
the utility model provides a throw material and prevent expansion bracket of falling injury which characterized in that: a pair of scissors supporting rods arranged in an X shape is arranged, two ends of each scissors supporting rod are respectively connected with a vertical supporting column, a circular ring-shaped hinge sleeve is arranged in the middle of each scissors supporting rod, and the hinge sleeves hinge the pair of scissors supporting rods through a hollow shaft.
Furthermore, each hinge sleeve is provided with a group of locking through holes, the two hinge sleeves can vertically penetrate through the locking through holes through rotation, and the locking pins are detachably in clearance fit with the penetrating locking through holes.
Furthermore, the upper end of the hollow shaft is provided with a flange which is clamped on the upper plane of the hinged sleeve at the top.
Furthermore, the lower end of the hollow shaft is connected with a funnel-shaped material guide cylinder.
Furthermore, the lower end of each supporting column is connected with a universal wheel of a brake.
The utility model has the beneficial effects that:
1. the utility model is stable and firm as a whole, can prevent the material bag from falling to hurt people and protect the life safety of operators.
2. The hinged scissors supporting rod can ensure that the scheme has the telescopic performance, reduces the occupied space and is convenient to store.
3. The universal wheel provided by the utility model can ensure that the device is convenient to move, and is time-saving and labor-saving.

Detailed Description
In order to make the present invention more clearly understood, the following description of the telescopic frame for preventing falling injury in feeding of the present invention is made with reference to the accompanying drawings, and the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
Referring to fig. 1 to 3, an expansion bracket for preventing falling injury during feeding comprises: a pair of scissors supporting rods 1 which are arranged in an X shape are arranged, two ends of each scissors supporting rod 1 are respectively welded with a supporting column 2, and the supporting columns 2 are vertically arranged and made of rectangular pipes. The bottom end of each supporting column 2 is connected with a universal wheel 6 with a brake. The middle position of each scissors supporting rod 1 is provided with a circular ring-shaped hinge sleeve 3, when 2 scissors supporting rods 1 are stacked together, the hinge sleeves 3 are coaxial and communicated, the hinge sleeves 3 hinge the pair of scissors supporting rods 1 through a hollow shaft 4, and each scissors supporting rod 1 can freely rotate around the hollow shaft 4.
As shown in fig. 1 and 2, a group of locking through holes 31 arranged in a ring shape is formed in the hinge sleeve 3, the two hinge sleeves 3 can vertically penetrate the locking through holes 31 through rotation, and the locking pin 5 is detachably in clearance fit with the penetrating locking through holes 31. The upper end of the locking pin 5 is provided with a circular ring 51, and the circular ring 51 is convenient to pull and prevents the locking pin 5 from falling from the locking through hole 31.
As shown in fig. 2 and 3, an annular flange 41 is provided at the upper end of the hollow shaft 4, and the flange 41 is clamped on the upper plane of the top hinge sleeve 3, so that the hollow shaft 4 is supported and the hollow shaft 4 is prevented from falling; in addition, the lower end of the hollow shaft 4 is connected with a funnel-shaped material guide cylinder 7 which is used as a channel for feeding the material bags.
The using method comprises the following steps:
1. move this expansion bracket directly over the retort dog-house (the retort is located the platform below) on the platform, drive scissors bracing piece 1 and rotate around hollow shaft 4 through promoting support column 2, make the expansion bracket expand to suitable position, lock scissors bracing piece 1 in the locking through-hole 31 that link up about rethread locking pin 5 penetrates, 6 areas of universal wheel are stopped, make the expansion bracket wholly firm motionless.
2. The driving removes the pocket directly over the dog-house, slowly falls the expansion bracket upper end, and operating personnel stands inside the expansion bracket, and the manual work is put the drain hole of pocket lower extreme in the hole of hollow shaft 4, opens the fag end on the pocket drain hole, and it is internal that raw and other materials are at the hole of hollow shaft 4 along guide tube 7 water conservancy diversion to the retort of below, reduces because of the extravagant loss that raw and other materials spill and cause.
3. After the feeding is completed, the empty material bag is removed, the brake of the universal wheel 6 is released, the telescopic frame is moved to the storage area of the tool, the locking pin 5 is taken out, the telescopic frame contracts, and the occupied space is reduced.
