Upper and lower bearing pin 33a, 33b run through three groups of U-groove bevel plates 35 and its two ends are fixed on the side plate of the two groups of U-groove bevel plates 35 in the outside, thereby a side of three groups of U-groove bevel plates 35 is mutually permanently connected, and form the post joint unit 3 that is one.Establish one group of drive link between the biside plate of each U-groove bevel plate 35, three U-groove bevel plates 35 are established three groups of drive link altogether, and every group of drive link comprises two drive link of arranging up and down.

The opposite side bottom of three groups of U-groove bevel plates 35 side by side is penetrated with coupling shaft 31, can the side plate of its adjacency be mutually permanently connected by bolt between two groups of adjacent U-groove bevel plates, for example, can adjacent side plates be fixed by two bolts that connect otic placode 34 in roof anchorage, to strengthen fixedly connected between the two adjacent groups U-groove bevel plate 35.Shown in Fig. 2 a, bolt 34b is passed successively connect otic placode 34, the side plate of outside U-groove bevel plate and the side plate and the fastening nut of middle U-groove bevel plate, connection otic placode 34 is fixed on the inside side plate of outside U-groove bevel plate 35, fixedly connected between the side plate with two adjacent U-groove bevel plates simultaneously.In addition, also can the inside side plate of outside U-groove bevel plate 35 and the side plate of middle U-groove bevel plate be interfixed, and will connect separately on the outer panel that otic placode 34 is fixed on outside U-groove bevel plate 35 by other two bolts by bolt 34b.

Shown in Fig. 2 e, the lower end that connects otic placode 34 is connected U-groove bevel plate 35 upper ends in the post joint unit, below by two bolt, it has the connecting end that protrudes in U-groove bevel plate upper end, connecting end is provided with hinging hole 34a, connecting end passes the bight of U-groove bevel plate corresponding in another post joint unit, top by the coupling shaft 31 that passes hinging hole 34a, and make connecting end hinged with the bight that another post saves U-groove bevel plate corresponding in unit, make that square column joint unit rotational can be gone up relatively by connection otic placode 34 in square column joint unit down.

The two end part that coupling shaft 31 stretches out post joint 3 outsides, unit are provided with rolling element 32, rolling element 32 is placed in first guiding groove 14 and second guiding groove 21 and along it and rolls, and makes it form vertical column 4 or makes it get back to installation position in the storage box so that lead by first guiding groove 14 and second guiding groove, 21 coupled columns joint unit 3.

The side plate 35a of each U-groove bevel plate 35 settles the bight of coupling shaft 31 to be circular arc, be convenient to post joint unit by level to the plumbness transition, perhaps by plumbness when the level transition, mutual interference does not take place between the unit in the adjacent post joint.The base plate 35b lower end of each U-groove bevel plate 35 forms a notch 37 in abutting connection with the position of side plate 35a circular arc part, when preventing 34 rotations of L shaped connection otic placode and the base plate of U-groove bevel plate interfere.

Although Fig. 2 is a, provided post joint unit 3 that three groups of U-groove bevel plates that connect side by side 35 form and structure with driving gear 15 of three corresponding gear teeth in 3, also can be according to the actual bearer needs, post joint unit 3 and four groups of post joint unit 3 that the U-groove bevel plate that connects side by side 35 forms that two groups of U-groove bevel plates that connect side by side 35 form are set, perhaps the more groups of post joint unit 3 that the U-groove bevel plate that connects side by side 35 forms.Two groups of chain links and driving gear 15 engagements are set in the post joint unit, chain link and driving gear 15 engagements more than two groups also can be set according to the height that post saves the unit, so that by driving gear 15 rotations, a drive post joint unit vertically joint connects a joint rise formation vertical column, such structure highly versatile, low cost of manufacture is convenient to industrial batch process.

As shown in Figure 3, transmission case 1 comprises biside plate 1a, the 1b that is arranged in parallel, settle transmission shaft 17 between the biside plate, fixed conveyor gear 15 on the transmission shaft, this driving gear 15 has three gear teeth 15a to cooperate above-mentioned post joint unit, three gear teeth 15a respectively with the roller 36a engagement of three chain links, driving gear 15 is rotated counterclockwise and drive post joint unit 3 moves up, driving gear 15 dextrorotations then drive post joint unit 3 move down.

Shown in Fig. 3,5, the inboard of biside plate 1a, 1b is provided with first guiding groove 14 respectively, and coupling shaft 31 is settled in the bight of post joint 3 lower ends, unit, and the two ends of coupling shaft 31 are mounted with rolling element 32 and can move along first guiding groove 14.

As shown in Figure 3, the biside plate 1a, the 1b that settle before and after transmission case 1 has, fixedly connected by a plurality of screw rod 13 between the biside plate, transmission shaft 17 is supported on a side of biside plate by bearing 18a, 18b, and transmission shaft 17 is driven by the motor (not shown) and rotates between biside plate.

The position of the bottom of biside plate close post joint storage box 2 is provided with the positioning plate 16 by bolt, can not break away from first guiding groove to guarantee post joint unit in moving process.The motion track of first guiding groove 14 vertical direction upper edge post joint unit in transmission case 1 extends, and as shown in Figure 5, comprises the curved portion of vertically extending lineal shape part and bottom.

When segmented column joint unit 3 is moved up by driving gear 15 drives, next post joint unit 3 can be dragged from storage box 2 by connection otic placode 34 and shift in the transmission case 1 along second guiding groove, 21 curved portions, move to the vertical position then and driven and move up, post joint unit is moved up one by one form vertical column 4 by driving gear 15.When transmission shaft 17 drives driving gear 15 on it and rotates, just promote to move up with the chain link of driving gear 15 engagements, driving on certain square column joint unit 3 moves up along first guiding groove 14, because the adjacent post in below saves unit 3 and should go up between the square column joint unit 3 by connecting around the L shaped otic placode 34 that is connected of last square column joint unit bottom rotation, thereby drive the follow-up of adjacent post joint unit, below, position in the side plate bottom near post joint storage box is provided with positioning plate 16, can play certain positioning action when post saves the unit transmission.

Working procedure and said process that post joint unit 3 moves down one by one are similar, and driving gear 15 turned clockwise and drove post joint unit and move down this moment, and one saves and connects one and save land and get back in the storage box.

As shown in Figure 1 and Figure 4, the storage box of post joint unit is interconnected by perpendicular frame 22a, 22b and crossbearer 23 and forms, and can ccontaining a plurality of post joints unit 3.

As shown in Figure 4, post joint unit storage box 2 comprises storage box 2a, following storage box 2b and transition case 2c, the a pair of second guide groove spare 20 is set in it, the second guide groove spare 20 comprises three segmentations, each box inside is fixed one section respectively, be respectively guide groove spare hypomere 20b, guide groove spare epimere 20a and the guide groove spare changeover portion 20c that is connected therebetween, guide groove spare hypomere 20b wherein, guide groove spare epimere 20a horizontal-extending also is symmetrically set, guide groove spare changeover portion 20c semicircular in shape, the second guide groove spare 20 has second guiding groove 21, i.e. each segmentation of the second guide groove spare 20 is respectively equipped with the guiding groove segmentation 21a to inner opening, 21b and changeover portion (not shown).
