According to the coal mining mode, underground tunneling construction is a prerequisite condition for coal mining. The existing coal mine tunneling work is limited by special construction environments and conditions, the operation of the tunneling machine is generally carried out by ' tunneling one branch ', the ' tunneling one branch ' means that the tunneling machine needs to be stopped every 0.8 or 1 meter when the tunneling machine tunnels forwards in a cutting kiln, the tunneling machine can be started to continue the cutting kiln tunneling operation after anchor net supporting operation is completed, the ' tunneling one branch ' and the two branches ' are stopped and supported in a better geological condition, the efficiency of the tunneling machine is greatly limited, in actual construction, the manual supporting stage occupies a longer time, and therefore, the single-shift footage cannot be rapidly improved.

Therefore, under the normal working condition, when the heading machine stops to carry out supporting operation, construction workers can rush to the head of the heading machine, even if measures are proper, the construction workers are matched with acquiescent skilled workers to carry out supporting operation, potential safety hazards cannot be considered and effectively prevented in a busy state, and various unexpected industrial accidents occur in actual construction, and the accidents are difficult to avoid.
In the actual coal mine tunneling construction, the tunneling machine only needs 10-15 minutes for cutting (1M) and advancing, and the manual supporting time needs more than 1 hour; therefore, the service efficiency of the heading machine is only about 20%, and 80% of mechanical energy is wasted, which is a main reason for limiting the operation efficiency of the heading machine. The coal mine safety operation regulation is a safety regulation established by practice and summary of blood teaching and training for a long time in coal mines. How to effectively implement the coal mine safety operation regulation and simultaneously achieve the liberation of productivity and improve the operation efficiency is a difficult problem. At present, in the industry, no equipment can simultaneously solve the restriction and limitation in the coal mine safety operation regulation, and no matter a full-face heading machine and a tunneling and tracing all-in-one machine can not break away from the restriction of the coal mine safety operation regulation, so that efficient and safe full-man-hour parallel operation is realized, and manual labor is liberated.

Compared with the prior art, the technical scheme of the invention has the following technical effects:
the invention relates to intelligent rapid coal mine tunneling equipment, which can also be called as coal mine rapid tunneling (SLV) equipment, wherein the SLV is English: the abbreviation WOrRing SLAE means "slay to listen". I.e. "servo" equipment.
The invention combines the patent application names of the inventor in 2019 as follows: the development and the improvement are carried out on the basis of a temporary shield support for a tunneling roadway (patent application number: 201910373735.1), the design and the practicability are combined through research and development for more than four years, and an artificial intelligence solution scheme for the whole process and the whole working hour utilization of tunneling construction operation is realized according to the research and development direction for specifically solving specific problems. The wheel type movable support is different from the prior ' temporary support equipment and use method of a roadway driving working face ' (application publication No. CN 109707430A) ' temporary support method of roadway driving ' (application publication No. CN 105971628A) '); the applications are described in the specification and the claims, the temporary support is a simple temporary support, the moving mode is a stepping type, the size change of any height and width of a driving tunnel cannot be realized, the balance of two sides cannot be stable, the layout and the mechanical action of the top can only be kept locally without a roof, the effect is not ideal, the constraint of coal mine safety regulations cannot be avoided, the surface looks wrong, the practical application cannot be solved, the footage is improved, and the technical problem of man-machine full-hour parallel operation is realized. Compared with the prior art, the two patent applications are both 'door' type frames, and have the defect that the secondary disasters caused by extrusion from the roadway side, particularly the sheet side cannot be resisted. The sheet nation can cause the whole bracket to be unable to move instantly, and the legs and the feet of the bracket have no friction and fixed resistance with the bottom plate and move towards the middle when stressed. The frame structure in the shape of a Chinese character 'men' only needs to be provided with the side in the tunneling construction, the landing legs and feet have no resistance and fall into paralysis at any time, and the problems of side and top falling in the tunneling construction often occur. The wheeled mobile support according to the invention is therefore fundamentally different from it. No matter the aspects of the model, the working method, the working principle, the working efficiency, the use function, the frame structure and the like, the method has completely different differences: therefore, the wheel type movable support adopts a square frame, the right bottom of the leg adopts a conical design, and the bottom plate is arranged under the action of gravity to enhance the extrusion resistance from the upper part; the bracket of the door-shaped frame structure moves, thrust is supplied by the parallel moving oil cylinders, but in an actual environment, balance movement is difficult to realize, and factors such as initial pressure from a top plate, extrusion of a bonding part, cutting of a bottom plate and the like are difficult to realize; can directly influence the smooth advancing. Practice proves that the wheel type movable support has enough strength to resist secondary disasters caused by sheet bonding because of adopting the square-shaped frame, and ensures that the whole support does not shift or deform.
2. The invention relates to a coal mine rapid tunneling (SLV) device, which is a special device specially created for coal mine tunneling construction to realize mechanization of the tunneling industry. The intelligent control and manual operation coexistence can be realized in tunneling roadways with different sections and different geological conditions.

13. Meanwhile, the shear power source support which is subsequently unfolded can be retracted forwards after the supporting operation is finished. The ditch digging gun head (154) completes the ditch digging in one time during the operation. The air duct pipeline, the water pipeline and the high-pressure air pipeline all synchronously move forwards.
14. The development machine needs the perfection and cooperation of the following systems while completing the synchronous uninterrupted operation: 1: a mobile ventilation system; 2: a mobile water supply system; 3: a mobile power supply system; 4: follow-up the transport system; 5: a material handling system; 6: a signal control system; 7: all permanent pipelines and cables are arranged, folded and communicated with a follow-up system during maintenance.
15. The various systems listed above must be perfectly and synchronously matched to possibly complete the task index of the rapid tunneling of the tunneling machine. Thus, the follow-up scheme is:
1) The air pipe is designed into a 20-meter telescopic air pipe, can extend and retract along with the support, and penetrates from the bottom of the operation platform to the head.
2) The belt is mainly transported in the roadway. A40-meter movable tail is designed, a telescopic air duct 129 is erected at the upper part of the tail, and a single-rail crane is arranged at the same time, so that the problems of cables, high-pressure air pipes, high-pressure water pipes and signal line pipes (all replaced by flexible rubber pipes) are solved.
3) The three-conveyer follow-up belt and the tail part of the bracket are connected with an outlet, and a belt bin is designed, so that the three-conveyer follow-up belt can be synchronously extended by 30 meters to meet the requirement of 24-hour footage.

Now, for the prior art, the invention has the characteristics that:
【1】 The existing frames are all in a shape like a Chinese character 'men', and the defects are that secondary disasters caused by extrusion from roadway sides, particularly bang parts, cannot be resisted. The sheet bonding can instantly cause the whole bracket to be incapable of moving, and the leg and the foot of the bracket and the bottom plate have no friction force or fixed resistance and move towards the middle when stressed. The portal frame structure has the advantages that as long as sheet bonding occurs in the tunneling construction, the landing legs and feet have no resistance and fall into paralysis at any time, and the problems of sheet bonding and top falling frequently occur in the tunneling construction.
In comparison, the movable automatic temporary shield support cannot be simply compared with the similar appearance, a square frame is adopted in the scheme, the right bottom of each leg is designed in a conical shape, and the right bottom is embedded into a bottom plate under the action of gravity, so that the extrusion resistance from the upper part is enhanced; in addition, the movement of the support is powered by the parallel moving oil cylinders, but the whole support cannot provide balance when the support actually moves, and a driver of any heading machine cannot cut the roadway bottom plate into a horizontal plane. Practice proves that the square frame is fundamentally different from the existing square frame from design to practical application; considering from the practical application aspect, the existing door-shaped frame can not realize the functions and purposes of the invention. The movable support in the invention adopts the square-shaped external frame, so that the movable support has enough strength to resist secondary disasters caused by bang, and the integral support is ensured not to shift and deform.
【2】 The wheel type and pillar double bearing mode is adopted, and the bracket moves forwards under the load of the bearing wheels when moving. When the support is moved in place, the support legs bear load, so that the support not only bears the self weight of the support, but also bears the pressure from sinking of the roadway roof. The wheel design is two-way, can overturn, but the diversion is convenient for wholly transport and install.
【3】 The double cooperation of mechanical balance power and cylinder shear power is adopted to determine sufficient stable power domination and complementation during movement.
【4】 Adopts a leveling tool bit. Two groups of leveling cutterheads are designed at the front end of the support, the function of each cutterhead is similar to that of a bed washing cutterhead, two bottom plate balance paths with the same width as the wheels can be horizontally cut out on the upper side and the lower side of a roadway, the movable wheels run on the bottom plate balance paths, and the upper side and the lower side of the movable wheels are kept in a forward balanced state forever. The movable support is always kept in overall balance and moves forwards in parallel according to rules.
【5】 Two protective wing secondary protection vertical posts are designed on the upper side and the lower side of the bracket, and three sets of gears are arranged on the upper side so as to fix the whole bonding net to be difficult to slide down in movement; and the operation of the bonding net can be influenced by the blockage of the slag coal after the sheet bonding.
【6】 The top of the bracket is provided with a first-level joist. The joist is scalable, can reciprocate, can guarantee balanced. The top net runs on the joist in balance to ensure absolutely no-empty top operation.
【7】 The primary joist is designed with 8 foldable wing supports, which is convenient for manual installation of steel belts.
【8】 The lower opening of the square frame is provided with a main ventilating duct and a follow-up belt frame. Reverse rails are arranged on two sides of the belt so as to facilitate the mechanical walking of the drill carriage platform in the support.
In summary, the following steps: under the background technology of the existing equipment in the current coal mine tunneling industry, the prior art does not provide comprehensive matching equipment which can really realize intelligent full-man-hour man-machine parallel operation, but the equipment provided by the invention can realize intelligent full-man-machine parallel operation.
Therefore, compared with the prior art, the invention has the following beneficial effects:
1. compared with the indexes that the single-month footage amount exceeds 1800 meters, the single-month footage amount can not realize the data in the prior art background such as a tunneling and anchoring all-in-one machine, a full-section heading machine, a shield machine and the like.
2. Completely eradicates the occurrence of safety accidents of the top plate and the sheet. The top and the two sides are pushed forwards after the protective net is laid, so that the safety threat of the sheet side and the falling top is avoided.
3. The project progress is fast, and the non-permanent tunnel does not generate maintenance cost any more.
4. The number of workers is small, 4 workers except for an anchoring agent arranged on a manual operation platform and a bolt are arranged on the manual operation platform, no operation worker is arranged on the whole roadway, and the operation workers are controlled by a remote computer.
5. The difficult problem caused by the severe conditions that the water spraying and water inflow amount of the tunneling roadway are prominent is effectively solved. Disposable plastic waterproof cloth can be laid on the shield support, and water is intensively guided to two sides and enters the ditch.
6. The camera 24 group is set on the movable bracket, the operation system executes the operation in the visual range, and the manual parking check can also correct the operation data.
7. The transportation is quick and the installation is convenient. When the working face is replaced, the walking wheels are disassembled and combined in groups, and the walking wheels are redirected and pushed manually. The mechanical vehicle can be dragged, so that the carrying is quick, a large amount of equipment installation time is saved, and the actual effect is improved.
