The assembly method of the invention comprises the following steps:

firstly, a fixed cylinder clamping ring 1-2 is sleeved on a fixed cylinder 1, anti-falling bosses 1-1 are welded at two ends of the fixed cylinder 1, a hoop is fixed in the fixed cylinder 1, then one end of a first-stage extension cylinder 3 (namely the extension cylinder with the smallest diameter) is installed at the head end of the extension cylinder 3, then the fixed cylinder clamping ring 1-2 and the fixed cylinder 1 are inserted from the tail end of the extension cylinder 3, then the other end of the first-stage extension cylinder 3 is installed at the tail end of the extension cylinder 3, an auxiliary tool with the first-stage extension cylinder is formed, and the fixed cylinder clamping ring is located between the anti-falling bosses and the limiting bosses of the first-stage extension cylinder at the moment.

If an extension cylinder is required to be added, an extension cylinder clamping ring 3-1 is required to be sleeved on the cylinder body of the first-stage extension cylinder 3 in advance when an auxiliary tool of the first-stage extension cylinder is assembled. Taking the example of adding the second-stage extension cylinder as an example, one end of the second-stage extension cylinder 3 is installed at the head end of the cylinder body of the second-stage extension cylinder 3, then the fixed cylinder snap ring 1-2, the fixed cylinder 1, the first-stage extension cylinder 3 and the extension cylinder snap ring 3-1 sleeved on the first-stage extension cylinder 3 are inserted from the tail end of the cylinder body of the second-stage extension cylinder 3, and then the other end of the second-stage extension cylinder 3 is installed at the tail end of the cylinder body of the second-stage extension cylinder 3. By analogy, the end plug of the last stage is directly utilized until the last stage after the length is needed without installing an extension barrel snap ring.

The use method of the invention comprises the following steps:

referring to fig. 8, assuming that the width of the cable trench cover 6 is similar to the length of the extension cylinder 3, the laid cable 5 is a hard core cable, and the laying steps are as follows:

a. the cable 5 is inserted into the fixed cylinder 1, fixed by the clamp, and then the auxiliary tool is retracted (i.e., the fixed cylinder is aligned with the two ends of the extension cylinder).

b. One cable trench cover 6 (a cover in fig. 8) is opened, and the present auxiliary tool is put into the cable trench 8 as shown in fig. 8 (a).

c. Promote extension section of thick bamboo 3 by the skin to the inlayer in proper order, make this appurtenance forward extend to maximum length, as shown in fig. 8 (B), take total 3 extension sections of thick bamboo in fig. 8 as the example, assume that the A apron is the 1 st apron, the B apron is the 7 th apron, after this appurtenance extended the limit, the operation personnel arrived 4 th apron departments in the place ahead, the last one-level extension section of thick bamboo 3 was held tightly to the arm through the hole for hoist 7 of the 4 th apron, appurtenance just was fixed by arm department this moment.

d. The operator at the open 1 st cover now inserts the cable so that the auxiliary tool is extended in the reverse direction to the maximum length, resulting in the state shown in fig. 8 (c), i.e. the fixed barrel 1 is ejected by the hard core cable.

e. The operator goes 7 th apron (B apron) departments in the place ahead and opens the apron, can take fixed section of thick bamboo 1, and the operator's of 4 th apron department arm is loosened a last level extension section of thick bamboo, and the operator of 7 th apron department withdraws extension section of thick bamboo 3 to initial condition in proper order, the state that fig. 8 (a) shows promptly.

f. And d, repeating the step c, the step d and the step e until the laying of the cable is completed.

According to the laying process, 7 cover plates which need to be opened originally only need to be opened for 2 cover plates, the length of the laid cable is larger, the ratio of the opened cover plates is smaller, 61 cover plates which need to be opened originally only need to be opened for 10 cover plates, the number of the opened cover plates is only one sixth of the total number of the cover plates, the laying efficiency of the cables in the reeling area of the iron and steel enterprises is greatly improved, and the cable laying cost is reduced.

When the suspended bridge frame is threaded, the auxiliary tool can be used, the auxiliary tool can be transmitted after being prolonged, and the auxiliary tool can be folded and bent when meeting a turning part.
