Description

TECHNICAL FIELD

[0001] The application relates to the technical field of roadway support construction equipment, and particularly relates to an adjustable roadway support equipment installation positioning support. BACKGROUND

[0002] In the roadway support construction process, drilling operation is a key process for ensuring support stability, and the operation quality and efficiency directly affect the progress and safety of the entire roadway support project. At present, roadway support drilling is mostly completed by using a drilling machine in cooperation with a positioning support, and the performance of the support directly affects drilling precision and equipment service life.

[0003] A patent for practical new type (CN215804391U) discloses an anchor rod drilling machine adjustable support for roadway support. The lifting frame and the adjusting rod cooperate to conveniently adjust the installation height of the anchor rod drilling machine; by means of the tail part and the drill bit adjusting assembly, the inclination angle of the drilling machine can be stably adjusted. The support has basic position adjustment and drilling machine fixing functions, but it is directly and rigidly connected with the anchor rod drilling machine. Since the thrust and the rotary torque will suddenly increase when the drill bit first contacts the rock surface in the initial drilling stage, high-frequency and high-intensity vibration will be generated. The vibration not only causes the drilling machine body to shake, causing problems such as drilling hole position deviation and irregular hole diameter, affecting the support construction quality, but also causes the parts to loosen, wear and even deform through the support conduction to the connecting parts for a long time, greatly shortening the overall service life of the drilling machine and the support. In addition, although some supports in the prior art are provided with a buffer structure, the buffer parts are mostly fixed damping, and if a large damping is set to ensure the vibration buffering effect in the initial drilling stage, the excessive fixed damping will be converted into additional drilling resistance in the drilling stage when the drill bit penetrates into the rock wall and the vibration is weakened, which significantly reduces the drilling efficiency, and it is difficult to balance the vibration protection and operation efficiency in the initial drilling stage, and cannot meet the core operation requirements of high precision and high efficiency in the roadway support construction.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] This embodiment provides an adjustable roadway support equipment installation and positioning bracket, such as... Figures 1-6 As shown, the mounting and positioning bracket includes a position adjustment structure 1 for adjusting the drilling position of the anchor drilling rig 2, and a propulsion structure 3 disposed on the position adjustment structure 1 and connected to the anchor drilling rig 2 for driving the anchor drilling rig 2 to advance along the drilling axial direction. The mounting and positioning bracket also includes a lifting seat 4 fixedly disposed on the propulsion structure 3, a connecting seat 5 disposed on the lifting seat 4 and fixedly connected to the anchor drilling rig 2, and an adaptive buffer structure 6 disposed between the lifting seat 4 and the connecting seat 5 for buffering the drilling of the anchor drilling rig 2. The adaptive buffer structure 6 includes a hydraulic damper 61 fixedly disposed on the lifting seat 4 and connected to the bottom of the connecting seat 5 for buffering, and an oil volume adjustment component 62 disposed on the propulsion structure 3 and connected to the hydraulic damper 61 for adjusting the oil volume in the hydraulic damper 61 as the anchor drilling rig 2 advances axially to adjust the buffering force.

[0019] In use, first, the drilling position of the roof bolter 2 is adjusted by the position adjusting structure 1, so that the roof bolter 2 is aligned with the target drilling position of the roadway wall, and then the operation of the position adjusting structure 1 is stopped, and then the driving force is provided by the advancing structure 3 arranged on the position adjusting structure 1 and connected with the roof bolter 2, so as to drive the roof bolter 2 to advance along the drilling axis step by step to carry out drilling operation. In the process of drilling by the advancing structure 3, the connecting seat 5 fixedly connected with the roof bolter 2 transmits the vibration of the roof bolter 2 to the self-adaptive buffering structure 6 arranged between the lifting seat 4 and the connecting seat 5, and the hydraulic damper 61 on the self-adaptive buffering structure 6 can buffer and damp the vibration generated by the drilling of the roof bolter 2 through its own characteristics, so as to reduce the damage to the roof bolter 2 and other parts of the support. At the same time, when the roof bolter 2 is driven by the advancing structure 3 to advance axially, and the roof bolter 2 generates high-frequency vibration when it first contacts the roadway wall, the hydraulic oil storage in the hydraulic damper 61 is sufficient, and the buffering force is the largest, so as to realize the effective protection of the equipment. With the gradual weakening of the vibration of the drill bit into the rock wall, the oil volume adjusting assembly 62 arranged on the advancing structure 3 and connected with the hydraulic damper 61 moves synchronously with the axial advancement of the roof bolter 2, which can reduce the oil volume in the hydraulic damper 61 in real time, dynamically reduce the buffering force to avoid excessive buffering affecting the drilling efficiency, and ensure the smooth and efficient drilling operation.

[0020] Specifically, the position adjusting structure 1 comprises a mechanical arm 11 and a height adjusting assembly 12 arranged at the end of the mechanical arm 11 and connected with the advancing structure 3, wherein the height adjusting assembly 12 comprises a fixed frame 121 fixedly connected with the mechanical arm 11, a lifting frame 122 slidably connected with the fixed frame 121 and connected with the advancing structure 3, a hydraulic cylinder one 123 fixedly installed on the fixed frame 121, and two guide rods one 124 fixedly installed on the fixed frame 121 and located on both sides of the hydraulic cylinder one 123. The lifting frame 122 is slidably sleeved on the guide rod one 124, and the piston rod of the hydraulic cylinder one 123 is fixedly connected with one side of the top of the lifting frame 122.

[0021] It should be noted that the mechanical arm 11 is fixed on the crawler-type walking mechanism, and the mechanical arm 11 and the crawler-type walking mechanism are prior art, and will not be described in detail here.

[0022] When drilling, the crawler-type walking vehicle drives the overall equipment to move flexibly in the tunnel to the target working area, and then the position adjusting structure 1 starts to work to adjust the drilling position of the anchor rod drilling machine 2. First, the multi-joint movement of the mechanical arm 11 drives the height adjusting assembly 12 at the end and the subsequent connected propulsion structure 3 and anchor rod drilling machine 2 to approach the approximate drilling area of the tunnel wall, and then the hydraulic cylinder one 123 on the fixed frame 121 starts and outputs a vertical driving force, the piston rod of which drives the lifting frame 122 slidingly sleeved on the guide rod one 124 on both sides of the fixed frame 121 to slide stably along the guide rod one 124. Then, the lifting frame 122 drives the connected propulsion structure 3 and anchor rod drilling machine 2 to realize accurate adjustment in the height direction, so that the anchor rod drilling machine 2 is accurately aligned with the target drilling position of the tunnel wall, laying a foundation for accurate positioning for subsequent drilling operation. The design of the guide rod one 124 can guide and limit the lifting frame 122 to avoid deviation of the lifting frame 122.

[0023] Preferably, the propulsion structure 3 includes a propulsion frame 31 slidingly connected to the lifting frame 122 away from one side of the guide rod one 124 and fixedly connected with the lifting seat 4, a hydraulic cylinder two 32 fixedly installed on the lifting frame 122 close to one side of the propulsion frame 31, and two guide rods two 33 fixedly installed on the lifting frame 122 and located at positions on both sides of the hydraulic cylinder two 32. The propulsion frame 31 is slidingly sleeved on the guide rod two 33, and the piston rod of the hydraulic cylinder two 32 is fixedly connected with the propulsion frame 31.

[0024] When the drilling machine 2 is accurately aligned with the target drilling position of the tunnel wall by the position adjusting structure 1, the propulsion structure 3 is started to realize the axial propulsion of the drilling machine 2. First, the hydraulic cylinder two 32 is started and outputs a stable axial driving force, and the piston rod thereof directly drives the propulsion frame 31 fixedly connected with the lifting seat 4 to move on the two guide rods two 33. Since the guide rod two 33 guides and limits the propulsion frame 31, deviation or shaking of the propulsion frame 31 during axial movement can be avoided, so that the propulsion frame 31 can drive the lifting seat 4, the connecting seat 5 and the drilling machine 2 to move stably along the drilling axis, thereby driving the drill bit to drill into the rock wall gradually, adapting to the drilling requirements of different depths.

[0025] Further, the hydraulic damper 61 includes a cylinder barrel 611 fixedly connected to the lifting seat 4, a piston one 612 slidingly connected in the cylinder barrel 611, a piston rod 613 longitudinally penetrating through the cylinder barrel 611 and fixedly connected with the piston one 612, and a buffer head 614 fixedly connected to one end of the piston rod 613 away from the piston one 612 and fixedly connected with the bottom of the connecting seat 5. The piston rod 613 is slidingly connected in the cylinder barrel 611, and the cylinder barrel 611 is filled with hydraulic oil.

[0026] It is worth mentioning that in order to ensure the buffering effect, the hydraulic dampers 61 are at least provided in two, and the plurality of hydraulic dampers 61 are uniformly distributed between the lifting seat 4 and the connecting seat 5; the design of the plurality of uniformly distributed hydraulic dampers 61 can be synchronously stressed, thereby absorbing the anchor rod drilling machine 2 vibration from different positions, forming a balanced buffering in all directions, and further improving the stability and buffering reliability of the drilling operation.

[0027] When the anchor rod drilling machine 2 vibrates during drilling operation, the vibration is transmitted to the anti-collision buffer head 614 through the connecting seat 5 fixedly connected with the drilling machine 2, then the anti-collision buffer head 614 conducts the vibration force to the piston rod 613 fixedly connected therewith, and drives the piston rod 613 to slide reciprocatingly in the cylinder 611 fixedly connected with the lifting seat 4 together with the piston one 612 fixedly connected at the end of the piston rod 613, at this time, the hydraulic oil filled in the cylinder 611 forms a damping resistance to the sliding of the piston one 612, and the vibration energy is absorbed by using the viscosity resistance and flow resistance of the hydraulic oil, thereby the vibration impact generated by the drilling of the drilling machine 2 can be weakened, and meanwhile the anti-collision buffer head 614 can avoid the rigid collision between the connecting seat 5 and the end of the piston rod 613, reduce the risk of component wear and tear, and realize the buffering protection of the drilling machine 2 and the related components of the support.

[0028] Further, the oil volume adjusting assembly 62 includes a fixed cylinder 621 fixedly installed on the lifting frame 122 and located on the side of the guide rod two 33 away from the hydraulic cylinder two 32, a piston two 622 slidingly connected in the fixed cylinder 621, a connecting rod 623 longitudinally penetrating through the top of the fixed cylinder 621 and fixedly connected with the piston two 622 for being connected with the advancing frame 31, and a hose 624 fixedly connected at the bottom of the fixed cylinder 621, both ends of the hose 624 are fixedly connected with the bottom end of the fixed cylinder 621 and the bottom side of the cylinder 611, respectively, the connecting rod 623 is slidingly connected with the fixed cylinder 621, in addition, the end of the connecting rod 623 away from the piston two 622 is fixedly connected with a connecting plate 625, and the connecting plate 625 is fixedly connected with one side of the advancing frame 31.

[0029] When the anchor rod drilling machine 2 is axially advanced by the propulsion structure 3, the connecting plate 625 fixedly connected to one side of the propulsion frame 31 will move axially synchronously with the propulsion frame 31, and with the movement of the connecting plate 625, it will drive the connecting rod 623 to slide along the fixed cylinder 621. When the propulsion frame 31 advances forward with the drilling machine 2 drilling a hole, the connecting plate 625 drives the connecting rod 623 to pull the piston two 622 to slide synchronously upward in the fixed cylinder 621, and the sliding of the piston two 622 increases the oil liquid containing space in the fixed cylinder 621 to generate a negative pressure suction force, which will synchronously suck the oil liquid in the cylinder 611 of the hydraulic damper 61 through the hose 624 fixedly connected to the bottom end of the fixed cylinder 621 and the bottom side of the cylinder 611, respectively, to reduce the oil liquid volume in the cylinder 611 to reduce the buffering strength. Conversely, when the drilling machine 2 retreats back after the drilling is completed, the connecting plate 625 drives the connecting rod 623 to push the piston two 622 to slide synchronously downward in the fixed cylinder 621, and the sliding of the piston two 622 compresses the oil liquid containing space in the fixed cylinder 621, which will also press the oil liquid in the fixed cylinder 621 into the cylinder 611 through the hose 624 to increase the oil liquid volume in the cylinder 611 for next use, finally realizing the effect of real-time adjustment of the oil liquid volume in the cylinder 611 and dynamic change of the buffering strength of the hydraulic damper 61, and adapting to the vibration intensity changes in different stages of drilling by the drilling machine 2.

[0030] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
