Main hydraulic prop 102 and secondary hydraulic prop 103 described in the present embodiment are hydraulic props, only to facilitate
Description and differentiation inborn ability are also known as main hydraulic prop 102, secondary hydraulic prop 103, are repeated no more hereinafter.
Embodiment 1
A kind of foundation-free installation system for fixing ribbon conveyer, including several main hydraulic pressure are provided in the present embodiment
Pillar 102, main hydraulic prop 102 are respectively arranged at the pedestal 201 of ribbon conveyer, and main hydraulic prop 102 can be in hydraulic oil
Driving effect under extend to 303 at the top of tunnel, and the pedestal 201 of ribbon conveyer is pressed by compressing at the top of tunnel 303
On the ground in tunnel 301, the fixation to ribbon conveyer is realized, in case the position of ribbon conveyer occurs during the work time
(sliding is mobile) is changed, danger is brought to coal mining.
Hydraulic prop commonly used in the prior art may be used in main hydraulic prop 102, and main hydraulic prop 102 can be in hydraulic pressure
It is extended under the driving effect of oil 303 at the top of tunnel, by compressing 303 at the top of tunnel so that the pedestal 201 of ribbon conveyer is tight
It is pressed on the ground in tunnel 301, increases normal pressure of the pedestal to 301 ground of tunnel, to increase the pedestal 201 of ribbon conveyer
Frictional force between ground, and it is larger than maximum, force (maximum load, including ribbon conveyer born when equipment operation
Its own gravity, the gravity of transported raw coal, belt tensile force etc. along ribbon conveyer length direction the sum of component), Ke Yifang
Just the installation and fixation of ribbon conveyer, fast, are efficiently realized, and can effectively ensure belt conveying in operational process
The position of machine does not change, and is conducive to ribbon conveyer normal operation.
Foundation-free installation system provided in this embodiment for fixing ribbon conveyer is substituted original using hydraulic device
The technology of pre-embedded anchoring bolts and the ribbon conveyer in Interal fixation tunnel 301, using technical solution provided in this embodiment
Installation and fixed ribbon conveyer are not necessarily to pre-embedded anchoring bolts, need to only use 301 bottom of tunnel without designing ground drawing
Cement pours smooth i.e. usable so that the installation procedure of ribbon conveyer is simpler, and installation cost is lower, can greatly shorten
The installation period of ribbon conveyer；In addition, in ribbon conveyer installation process, also saves mounting hole and adjusted with foundation bolt
The process of alignment reduces the workload in installation and fixation procedure without using nut or welding steel fixed equipment, can be with
Effectively improve working efficiency.
It is former according to the length of ribbon conveyer, the angle of inclination in tunnel 301, Leather Belt Conveyance in Practical Project
The parameters such as speed, capacity when coal, technical staff or designer can easily calculate the number of required main hydraulic prop 102
Mesh and/or installation site etc., to realize to ribbon conveyer safety, firm fixation so that this is for fixing belt conveying
The foundation-free installation system of machine, more meets the actual conditions of use site, and application range is wider, and applicable situation is more.
In a kind of preferably scheme, several main hydraulic props 102 can be divided into several hydraulic pressure units 101, often
Include two main hydraulic props 102 in a hydraulic pressure unit 101, two main hydraulic props 102 difference in same hydraulic pressure unit 101
The both sides of the pedestal 201 of ribbon conveyer are set to, and two main hydraulic props 102 in same hydraulic pressure unit 101 are mutually flat
Row.I.e. in same hydraulic pressure unit 101, two main hydraulic props 102 are separately positioned on 201 both sides of pedestal of ribbon conveyer, and
On mutual corresponding position, in fixed ribbon conveyer, two main hydraulic pressure branch in hydraulic pressure unit 101 are driven using hydraulic oil
Column 102 extends to 303 at the top of tunnel, is in contact and compresses with 301 top of tunnel, to be produced to the pedestal 201 of ribbon conveyer
Raw normal pressure or positive pressure force component straight down；Such setting：On the one hand be conducive to be arranged at 101 position of hydraulic pressure unit
The fixation of ribbon conveyer is more firm, and on the other hand, tunnel 301 in the prior art is typically domes, i.e., at the top of tunnel
303 be arc, if a main hydraulic prop 102 is only arranged in hydraulic pressure unit 101, tunnel is compressed in main hydraulic prop 102
During 301 tops, it is possible to create perpendicular to the horizontal force of ribbon conveyer length direction, be easy to cause belt conveying
Machine is displaced sideways or sliding, very unfavorable for the fixation of ribbon conveyer, and mutually flat using two in hydraulic pressure unit 101
After capable main hydraulic prop 102, it is possible to create the horizontal force perpendicular to ribbon conveyer length direction can be at two
It cancels out each other between main hydraulic prop 102 (because direction is opposite), so that the fixation to ribbon conveyer is more stable.
Optionally in scheme, when the number of hydraulic pressure unit 101 is greater than or equal to 2, at least there are two in hydraulic pressure unit 101
Main hydraulic prop 102 be obliquely installed along the length direction of ribbon conveyer, and the inclination side of at least one hydraulic pressure unit 101
To different from remaining hydraulic pressure unit 101；I.e. during fixed ribbon conveyer, in addition to making in some hydraulic pressure units 101
Main hydraulic prop 102 be vertically arranged except, can also splayed or herringbone be set along the length direction of ribbon conveyer
Support construction, for example, as shown in Figure 1, two hydraulic pressure units 101 being obliquely installed of length direction along ribbon conveyer can be with structure
At splayed support construction, and as shown in Fig. 2, along ribbon conveyer two hydraulic pressure units 101 being obliquely installed of length direction
Herringbone support construction is may be constructed, such setting can make belt conveying in the length direction along ribbon conveyer
The fixation of machine is more firm, is not in the case where ribbon conveyer is moved or slided along tunnel 301, is particularly suitable for arch lane
Road 301, and the larger occasion in angle of inclination in tunnel 301.
In a kind of preferably scheme, including two hydraulic pressure units being obliquely installed along the length direction of ribbon conveyer
101, the angle of inclination of one of hydraulic pressure unit 101 can be 75 degree, and the angle of inclination of another hydraulic pressure unit 101 can be
105 degree；That is the angle of inclination of two hydraulic pressure units 101 is complementary, to realize preferably fixed effect.
Further, further include two secondary hydraulic props 103 in each hydraulic pressure unit 101, the pair hydraulic prop 103 divides
Not corresponding with two main hydraulic props 102 in hydraulic pressure unit 101, secondary hydraulic prop 103 is mainly used for adjusting corresponding main liquid
Press the direction of pillar 102 (i.e. along the angle of the length direction of ribbon conveyer).Using secondary hydraulic prop 103 can easily by
Corresponding main hydraulic prop 102 is adjusted to suitable or setting angle, and main hydraulic prop 102 is such as adjusted to vertical direction, or
The angle etc. that main hydraulic prop 102 is adjusted to tilt with the length direction of ribbon conveyer；On the one hand, it can substantially reduce
Labor intensity shortens main hydraulic prop 102 and installs the time in place, improves efficiency, on the other hand, can be more accurate, reliable
It is very convenient by the adjusting of main hydraulic prop 102 to scheduled Support Position.
Further include pedestal 104 further in scheme, one end of the pedestal 104 is removably connected to the main liquid
Pillar 102 is pressed, and is connected as one with main hydraulic prop 102, when main hydraulic prop 102 extends, pedestal 104 can be in main liquid
It presses and contacts and compress under the induced effect of pillar 102 303 at the top of tunnel, to the pressure using 301 top of tunnel to pedestal 104
