Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A multifunctional bolting jig according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 5, the multifunctional bolting jig according to the embodiment of the present invention includes a base 1, a rotation shaft 2, a first driving assembly 3, a grouting assembly 4, a second driving assembly, and a no-return assembly 6.

The rotating shaft 2 is rotatably connected to the base 1, an axis of the rotating shaft 2 is arranged along a first direction (a front-back direction shown in fig. 1), a through hole 21 is formed in the rotating shaft 2, the axis of the through hole 21 is arranged along the first direction, the first driving assembly 3 is connected to the base 1 and is in transmission connection with the rotating shaft 2, and the first driving assembly 3 is used for driving the rotating shaft 2 to rotate by taking the axis of the rotating shaft 2 as a rotation center. It will be appreciated that the shaft 2 is adapted to be connected to a hollow rock bolt or drill rod (not shown) for use in construction to perform drilling and pre-tensioning operations, for example, as shown in figures 1 and 4, the hollow rock bolt may be inserted into the shaft 2 from the rear end of the shaft 2. Furthermore, it will be appreciated by those skilled in the art that the bolt hole is drilled in a direction opposite to the direction in which the bolt is pre-tensioned after drilling. For example, if the rotating shaft 2 rotates forward, the anchor rod is driven to perform drilling operation. After the drilling and anchoring of the anchor rod are completed, the rotating shaft 2 rotates reversely to drive the anchor rod to perform pre-tightening operation.

The grouting assembly 4 is slidably connected to the base 1, the grouting assembly 4 has a fluid passage 41, an inlet of the fluid passage 41 is adapted to communicate with a delivery pump so that the delivery pump can pump fluid such as water, an anchoring agent, etc. into the fluid passage 41, and an outlet of the fluid passage 41 communicates with the rotating shaft 2 so that fluid (such as water or an anchoring agent) in the fluid passage 41 can be delivered into the rotating shaft 2. Preferably, the outlet ends of the fluid passages 41 abut one end of the hollow anchor so that fluid in the fluid passages 41 can be delivered directly into the hollow anchor and leakage into the through bore 21 is minimized.

The second drive assembly is connected in base 1 and is connected with slip casting subassembly 4 transmission, and the second drive assembly is used for driving slip casting subassembly 4 and moves along first direction, and when slip casting subassembly 4 was to the stock in fluid delivery, slip casting subassembly 4 offseted with the stock, and when the stock pretension, slip casting subassembly 4 and stock separation and interval had the distance, prevented that slip casting subassembly 4 and stock from taking place to interfere.

The check assembly 6 is connected in the fluid passage 41, and the check assembly 6 is used for enabling the liquid in the fluid passage 41 to flow into the through hole 21 in a single direction, so that the situation that the fluid in the through hole 21 or the anchor rod flows back into the fluid passage 41 to affect the anchoring effect is avoided.

According to the multifunctional anchor rod supporting drill box disclosed by the embodiment of the invention, the rotating shaft 2 is driven to rotate by the first driving assembly 3, so that the construction operation of anchor rod drilling and pre-tightening is realized; the fluid medium is conveyed to the anchor rod through the fluid channel 41 of the grouting assembly 4, so that the anchoring operation of the anchor rod is realized; the grouting component 4 is driven to move by the second driving component, so that the grouting component 4 is prevented from interfering with the anchor rod, and meanwhile, the fluid channel 41 of the multifunctional anchor rod supporting drill box is static relative to the surrounding environment during grouting and is suitable for conveying fluid materials which are easy to react and easy to volatilize and dissipate; fluid in the through-hole 21 or the anchor rod is prevented from flowing back into the fluid passage 41 by the check assembly 6.

As shown in fig. 5, in some embodiments, the check assembly 6 includes a valve body 61, a valve core 62 and a magnetic member 63, the valve body 61 has a passage, the valve core 62 and the magnetic member 63 are both disposed in the valve body 61, the valve core 62 has a blocking position and a conducting position, the magnetic member 63 is used for driving the valve core 62 to switch between the blocking position and the conducting position, in the blocking position, the magnetic member 63 applies a traction force to the valve core 62 under the action of its own magnetic force, so that the valve core 62 contacts with the magnetic member 63 and blocks the passage, and in the conducting position, the valve core 62 is separated from the magnetic member 63 and conducts the passage.

During operation of the bolting work equipment, when fluid flows along the fluid passage 41 toward the through hole 21, the pressure of the fluid overcomes the magnetic force of the spool 62 and the magnetic member 63 and then flushes the spool 62 and the magnetic member 63, thereby conducting the fluid passage 41. When there is no fluid flowing to the through hole 21 in the fluid passage 41, or when the fluid flows in the reverse direction, the fluid passage 41 is blocked by the valve element 62 contacting the magnetic member 63 under the action of the pulling force of the magnetic member 63 and/or the pressure generated by the fluid flowing in the reverse direction, so as to prevent the fluid from flowing back.

As shown in fig. 5, further, the inner peripheral wall of the valve body 61 has an annular fixing portion 611, the magnetic member 63 is connected to the fixing portion 611, the valve core 62 passes through the fixing portion 611, the valve core 62 has a blocking portion 621 and a limiting portion 622 which are connected, the limiting portion 622 is used for limiting the valve core 62 to be separated from the valve body 61, in other words, the limiting portion 622 can limit the moving range of the valve core 62 along the axial direction of the valve body 61, when the valve core 62 is located at the blocking position, the blocking portion 621 is adsorbed on the magnetic member 63, so that the valve core 62 and the magnetic member 63 form a circular line seal, and thus the liquid backflow phenomenon during the operation of the bolting construction equipment is further avoided.

As shown in fig. 1, in some embodiments, there are multiple fluid passages 41, the multiple fluid passages 41 are not communicated with each other, there are multiple check assemblies 6, the multiple check assemblies 6 correspond to the multiple fluid passages 41 one by one, and the check assemblies 6 are connected in the corresponding fluid passages 41. It can be understood that, by the one-to-one correspondence of the plurality of fluid passages 41 and the plurality of media sources, the plurality of fluid passages 41 can provide media according to the requirements of actual working conditions. For example, during drilling, one of the fluid passages 43 delivers water to the rock bolt to clear away the coal slag produced during drilling, during bolting, the water supply is shut off, and the other fluid passage 41 supplies anchoring agent to the rock bolt to anchor the rock bolt and surrounding rock together.

As shown in fig. 1-4, in some embodiments, the grouting assembly 4 further includes an anchoring member 42, the anchoring member 42 is slidably connected to the base 1, the anchoring member 42 is drivingly connected to the second driving assembly, a portion of the anchoring member 42 is located in the through hole 21 and is engaged with the sidewall of the through hole 21 to seal the front end of the through hole 21 and prevent the fluid in the through hole 21 from leaking from the front end of the through hole 21 to cause unnecessary fluid loss, and the fluid passage 41 is disposed in the anchoring member 42.

The limiting columns 7 and the limiting holes 421 limit the anchoring pieces 42 to rotate along the circumferential direction of the rotating shaft 2, and the fluid in the fluid channel 41 is prevented from shaking and losing efficacy.

As shown in fig. 1 to 4, in some embodiments, the multifunctional bolting box further includes a bolt adapter 8, the bolt adapter 8 is detachably connected to one end of the rotating shaft 2 far away from the grouting assembly 4, the bolt adapter 8 is used for connecting the rotating shaft 2 and the bolt, a through groove matched with the pre-tightening nut is formed in an inner wall of the bolt adapter 8, when the bolt is inserted into the bolt adapter 8 and the through hole 21, the pre-tightening nut on the bolt abuts against a circumferential wall of the through groove, so that the bolt adapter 8 drives the pre-tightening nut on the bolt to rotate relative to the bolt when the through hole 21 is reversed, and thereby pre-tightening the bolt.

In some embodiments, the first driving assembly 3 includes a first driving member 31, a first transmission member 32 and a second transmission member 33, the first transmission member 32 is connected to the output shaft of the first driving member 31, the second driving member 5 is connected to the rotating shaft 2, and the second driving member 5 is in transmission fit with the first driving member 31.

In some embodiments, the first driving member 31 is a hydraulic motor, the first driving member is a driving gear sleeved on an output shaft of the hydraulic motor, and the second driving member is a driven gear sleeved on the rotating shaft and engaged with the driving gear, so that the hydraulic motor drives the driven gear to rotate by the driving gear to drive the rotating shaft 2 to rotate. It can be understood that, when the hydraulic motor rotates positively, the hydraulic motor drives the rotating shaft 2 to rotate negatively through the driving gear and the driven gear, and when the hydraulic motor rotates negatively, the hydraulic motor drives the rotating shaft 2 to rotate positively through the driving gear and the driven gear.

In some embodiments, the second drive assembly comprises a second driver 5, the second driver 5 being at least one of an electric cylinder, an air cylinder, a linear hydraulic motor. For example, the second driving member 5 is a linear hydraulic motor, the linear hydraulic motor is connected to the base 1, an output shaft of the linear hydraulic motor is connected to the grouting assembly 4, and the output shaft of the hydraulic motor moves in the front-rear direction to drive the grouting assembly 4 to move in the front-rear direction.
