Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the structure of the utility model jacknife mast is, comprises the epimere 1 and hypomere 2 that can break, and epimere 1 is fixing girder structure, and width dimensions is relatively little;
Hypomere 2 is K type derrick, the multiple lugs hinged with pull bar 5 are provided with inside hypomere 2 liang of side frame body front columns, during travel position, the lug one_to_one corresponding on hypomere 2 liang of side frame bodies and be connected with pull bar 5 (see Fig. 6), prevents hypomere 2 front column place in transportation from launching and tilting, multiple link 10 is provided with inside hypomere 2 liang of side frame body backs, each link 10 is provided with three pin-and-holes triangular in shape, a back of the body crossbeam 3 is hinged with respectively by bearing pin 3 11 and bearing pin 4 12 in two pin-and-holes up and down inside time in working order, bearing pin 3 11 is wherein steady pin, as rotating shaft, bearing pin 4 12 is as removable pin, and dismounting as required, realizes the folding of each back of the body crossbeam 3 or fixing (see Fig. 4 or Fig. 6), back of the body crossbeam 3 is symmetrically set with along interval, hypomere 2 both sides certain altitude that multipair (it is six right to show in Fig. 1 embodiment, to ensure the reliability of installing), a diagonal member 4 is symmetrically arranged with respectively between each back of the body crossbeam 3 upper and lower surface and two side frame bodies, each diagonal member 4 is all hinged with hypomere 2 framework of this side by a bearing pin 6 14, each back of the body crossbeam 3 inner termination correspondence is provided with a pair oscillating bearing 6, and carry on the back two the corresponding snap-ins of oscillating bearing 6 of crossbeam 3 mated condition at often pair and be inserted with bearing pin 29 and bearing pin 5 13 respectively, see Fig. 7, by fixed for often pair of back of the body crossbeam 3, each back of the body crossbeam 3 rear end face is all provided with a positioning seat 7, and when often pair of back of the body crossbeam 3 inwardly folds into certain angle, two positioning seats 7 are engaged, and now, the pin-and-hole of two positioning seats 7 aligns and by bearing pin 1 grafting.
The otic placode of link 10 is provided with 3 groups of pin-and-holes, two groups of pin-and-holes of relative inner are for carrying on the back the connection of crossbeam 3 when normal operating conditions uses, one group of pin-and-hole of opposite exterior lateral sides folds rotating hole on rear and back of the body crossbeam and aligns after derrick, put on bearing pin 4 12, the one-sided of hypomere 2 can be made to keep compact state with back of the body crossbeam 3.
Use procedure of the present utility model is,
See Fig. 8, derrick does not carry out any folding dismounting in open and flat area, can integral installation transport on trailer.
Road conditions can not meet the haul of full-scale large span entirety when requiring, upper and lower for derrick two sections can be split, see Fig. 9, epimere 1 width dimensions is little, directly employing truck or trailer transportation.
When hypomere 2 transports, width dimensions is larger, need to remove bearing pin 4 12, bearing pin 5 13 that often pair of back of the body crossbeam 3 connects, by householder methods such as cranes, the bearing pin 29 that back of the body crossbeam 3 connects along middle part is bent inwards, owing to installing the monaural plate hole of bearing pin 29 built with oscillating bearing 6, the back of the body crossbeam 3 on both sides can being made along bearing pin 29 center simultaneously to inward side to turning back, making each diagonal member 4 at the arranged on left and right sides face of derrick hypomere 2 and back all to the closing of derrick center, seeing Fig. 5; After often pair of back of the body crossbeam 3 folds and puts in place, bearing pin 1 is loaded onto after this is tight to positioning seat 7 closing of back of the body crossbeam 3 rear end, outside the triangle of link 10, in a pin-and-hole, bearing pin 4 12 is installed simultaneously, back of the body crossbeam can be made to keep folded state, then couple together with the front column of pull bar 5 by hypomere 2 arranged on left and right sides face, the derrick after folding can be made to become a rigid rack body, see Fig. 6, substantially reduce width dimensions like this, meet hypomere 2 and carry out with less width dimensions the requirement that entirety drags, see Figure 10.
After derrick moving puts in place, remove connecting rod 5, remove bearing pin 1, bearing pin 10, by householder methods such as cranes, back of the body crossbeam 3 is stretched exceptionally straight, derrick hypomere is launched, installs bearing pin 4 12, bearing pin 5 13, then derrick hypomere is connected with epimere, install all the other annexes, derrick body is just in complete using state to be hoisted.
