In description of the present utility model, close the orientation of indications such as term " vertically ", " laterally " or position is based on orientation shown in the drawings or position relation, it only is the utility model rather than require the utility model therefore can not be interpreted as for convenience of description with specific orientation structure and operation to restriction of the present utility model.
As illustrated in fig. 1 and 2, comprise pit shaft 1, be arranged on the buntons 3 in the pit shaft and vertically be arranged on the seamless cage guide 2 of integral type on the buntons 3 according to the vertical shaft for mine equipment of the utility model embodiment.As shown in Figure 1, be provided with two elevators 100 in pit shaft 1, elevator 100 is provided with guide groove 200, and guide groove 200 cooperates with seamless cage guide 2, so that elevator 100 moves up and down in pit shaft 1.
Seamless cage guide and common cage guide are that in the fundamental difference on stressed seamless cage guide bears bigger thermal stresses.The thermal stresses of cage guide is to change in the cage guide temperature and produce under the situation that cage guide can not freely stretch.If in the cage guide temperature is T
0The time be that L and the two ends that are in the cage guide of free state are completely fixed with a segment length, when the cage guide temperature with respect to T
0When rising or decline Δ T, be equivalent to the cage guide compression or the corresponding free stroke Δ L that stretched, so produced longitudinal temperature power in the cage guide.
The free stroke Δ L of cage guide is:
ΔL＝α×ΔT×L (1)
ΔT＝T-T
0
By Hooke's law as can be known, the thermal stresses σ of cage guide
TFor:
σ
T＝E×ε＝E×ΔL/L＝E×α×ΔT (2)
Wherein, E is the modulus of elasticity of square steel cage guide, is 2.1 * 10
5MPa; α is the linear expansion coefficient of square steel cage guide, is 11.8 * 10
-6(1/ ℃); Δ T be with respect to the range of temperature of zero stress cage guide temperature (℃), heat up on the occasion of, be called temperature rise; T

0Be called locking temperature.
From formula (2) as can be seen, cage guide temperature inside stress is only relevant with the range of temperature Δ T of cage guide, and irrelevant with the length of cage guide, the basic principle of Here it is seamless cage guide.In other words, as long as the stress that control cage guide variations in temperature causes (is more or less the same between the maximum temperature of general pit shaft and the minimum temperature, particularly for the pit shaft below the 200m, the temperature difference generally only is 10 ℃), the laying length of seamless cage guide just can endless, the basic principle that Here it is lays seamless cage guide.
Cage guide temperature inside power P
TFor:
P
T＝A×σ
T＝A×E×α×ΔT＝247.8×A×ΔT (3)
Wherein, A is the cross sectional area (cm of cage guide
2).
From formula (3) as can be seen, even in one day, the TEMPERATURE FORCE of seamless cage guide also constantly changes along with the cage guide variation of temperature.And locking temperature T
0, in general be a constant, be the benchmark of determining the TEMPERATURE FORCE of seamless cage guide.Therefore, in the management of seamless cage guide, most important is not the TEMPERATURE FORCE of determining a certain moment, but determines actual locking temperature T exactly
0If, because determined actual locking temperature T
0(being zero stress cage guide temperature), the cage guide range of temperature in the time of just can determining any cage guide temperature, and then determine corresponding TEMPERATURE FORCE.
