Description

Technical Field

[0001] This invention belongs to the field of anchor drilling rigs, specifically relating to a new type of quick-opening anchor chamber for automatic anchoring operations. Background Technology

[0002] In response to the national strategy for building intelligent coal mine equipment, automated bolt drilling rigs have been developed, designed, and gradually promoted for use. As the core system of the bolt drilling rig, the drill frame system is responsible for drilling and anchoring. Under harsh underground conditions, long-term operation on the coal seam roof inevitably leads to the introduction of external impurities into the drill frame. The internal structure of the automated drilling rig is complex. If the drill frame is not inspected and maintained in a timely manner after operation, some of the more delicate mechanisms may malfunction.

[0003] Therefore, the fixed inspection and maintenance of the drill frame after each shift, as well as the troubleshooting of random drill frame malfunctions during operation, are issues that must be considered in the structural design of automatic drilling rigs. Existing automatic anchor bolt drilling rigs are equipped with an anchor bolt chamber to store multiple anchor bolts in order to achieve continuous automatic anchoring operations. The anchor bolt chamber and the main frame constitute the outer frame of the drill frame. However, the anchor bolt chamber and the main frame of the drill frame are fixed welded structures. Once the above-mentioned problems occur, due to the complex integrated characteristics of the internal structure of the drill frame, there is insufficient space for maintenance, resulting in low efficiency of daily inspection and fault repair, and the inability to efficiently and promptly resolve sudden faults. This leads to the inability of the whole machine to operate normally, reducing support efficiency, and consequently affecting the tunneling efficiency of the supporting operations, causing an imbalance in the mining ratio, and seriously affecting the tunneling and coal mining efficiency. Summary of the Invention

[0004] The purpose of this invention is to enhance the inspection and maintenance performance of the automatic drilling rig and drilling frame, shorten the downtime caused by malfunctions during the support process, and improve support efficiency.

[0005] The present invention provides the following technical solution: a new type of quick-opening anchor bolt chamber for automatic anchoring operation, comprising a main frame of the drilling frame, an anchor bolt chamber, a rotating shaft mechanism, a locking mechanism, and a locking mechanism fixing block; one side of the anchor bolt chamber is connected to the main frame of the drilling frame through the rotating shaft mechanism, and the other side is unlocked and locked to the main frame of the drilling frame through the locking mechanism and the locking mechanism fixing block.

[0006] Furthermore, the locking mechanism is installed in the anchor bolt chamber, and the locking mechanism fixing block is installed in the main frame of the drill frame;

[0007] The locking mechanism includes locking claws, a push-out switch, spring I, and spring II. One locking claw is positioned at the top and one at the bottom, with the middle of the locking claw hinged to the anchor bolt chamber. Spring I is installed between the two locking claws. Using the hinge axis of the locking claws as the boundary, spring I is located on the side closer to the locking mechanism's fixing block. A barb is provided on the outer side of the locking claw. Spring I spreads the two locking claws apart, causing the barbs to lock into the hole. The side of the locking claw closest to the fixing block is the head, and the side furthest from the fixing block is the tail. The wedge-shaped structure of the locking claw head extends to the barb, facilitating the convergence of the two locking claws and their insertion into the hole. Chamfers are provided on the adjacent sides of the tails of the two locking claws, allowing the push-out switch to insert and spread the two locking claws apart, causing the barbs to converge and lose their locking function.

[0008] The locking mechanism fixing block has a locking hole that mates with the locking claw;

[0009] The push-out switch is located between the tails of the two locking claws. The head of the push-out switch is pointed. The push-out switch is slidably installed in the guide hole on the anchor bolt chamber. A spring II is fitted on the push-out switch. One end of the spring II abuts against the boss at the tail of the push-out switch, and the other end abuts against the anchor bolt chamber. The spring II applies a thrust to the push-out switch when it resets after unlocking the locking claws. The push-out switch is equipped with a limit ring, which stops at the anchor bolt chamber and limits the stroke of the spring II pushing the push-out switch.

[0010] Furthermore, the rotating shaft mechanism includes a lubricating oil cup, a locking plate, an upper rotating plate, an intermediate shaft, a ball bearing plate, and a lower rotating plate; the upper and lower rotating plates are welded to the main frame of the drill frame, and the ball bearing plate is welded to the anchor bolt chamber; the intermediate shaft passes through the shaft holes of the lower rotating plate, the ball bearing plate, and the upper rotating plate, and the locking plate and the intermediate shaft are connected as a whole by threaded fastening; the ball bearing plate meshes with the upper and lower rotating plates; the lubricating oil cup can provide oil lubrication for the rotating shaft mechanism.

[0011] Furthermore, the main frame of the drill frame consists of a main plate, side plates, and a solenoid valve block mounting plate; the side plates are welded to the main plate to form an outer frame, and the solenoid valve block mounting plate is fastened to the main plate to provide assembly space for the solenoid valve of the drill frame.

[0012] Furthermore, the anchor bolt chamber is a rectangular frame formed by welding two horizontal plates and two vertical plates together.

[0013] Furthermore, the main frame of the drill frame also includes cantilever arm I and cantilever arm II; cantilever arm I and cantilever arm II are respectively connected to the side plates on both sides, and the extended end of cantilever arm I is connected to the rotating shaft mechanism, and the extended end of cantilever arm II is equipped with a locking mechanism fixing block.

[0014] Furthermore, the ball plate has two layers of concentric ball rings.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] This invention relates to the design improvement of automated bolt drilling rigs for coal mine roadway anchoring operations, significantly increasing the maintenance and repair space of the drilling frame and greatly improving the overall equipment maintenance and repair efficiency, thereby significantly enhancing support efficiency. The main innovations of this invention are the double-layer ball bearing shaft mechanism design and the automatic locking mechanism for closing the chamber, which are easy to operate. It improves the efficiency of fixed maintenance and repair of the drilling frame after each shift, increases the equipment maintenance space in the limited underground space, enhances the applicability of various tools, and enables efficient and timely resolution of daily maintenance and sudden malfunctions, thus improving support efficiency and enhancing roadway excavation and coal mining efficiency.

[0017] The intermediate shaft of the rotating shaft mechanism passes through the center of each plate and is connected to the locking plate by threads to achieve overall fastening of the rotating shaft mechanism; a double-layer ball structure is designed, with the upper and lower layers of balls meshing with the grooves of the upper and lower rotating plates respectively, and the two layers of balls working simultaneously, which enhances the reliability of the rotating shaft mechanism; a lubricating oil cup is designed to achieve periodic oil lubrication of the rotating shaft mechanism, thereby improving the service life of the rotating shaft mechanism.

[0018] When the drill frame is opened for maintenance, press the push-out switch between the two locking claws. As the locking claws close, the main frame of the drill frame is separated from the anchor bolt chamber. After maintenance, the anchor bolt chamber is closed directly. Under the action of external force, the locking claws and the locking mechanism fixing block come into contact with each other, causing spring I to be compressed. After the locking claws pass through the groove of the locking mechanism fixing block, they open and limit each other with the locking mechanism fixing block to achieve locking. At the same time, under the action of spring II, the push-out switch is pulled back and automatically resets. Attached Figure Description

Detailed Implementation

[0025] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] like Figure 1 , Figure 2 As shown; a new type of quick-opening anchor bolt chamber for automatic anchoring operation includes a drill frame main frame 1, an anchor bolt chamber 2, a cantilever arm, a locking mechanism fixing block 5, and a rotating shaft mechanism 6; the drill frame main frame 1 serves as the main load-bearing support part of the drill frame and is connected to the anchor bolt chamber 2 through the cantilever arm.

[0027] Specifically, the cantilever arm consists of cantilever arm I3 and cantilever arm II4. One end of cantilever arm I3 is connected to the main frame 1 of the drill frame, and the other end is connected to the rotating shaft mechanism 6. The shaft plate extending from the rotating shaft mechanism 6 is welded to the anchor bolt chamber 2. The other end of cantilever arm II4 is machined with a locking mechanism fixing block 5, which is used to lock the main frame 1 of the drill frame and the anchor bolt chamber 2.

[0028] Further structural decomposition description of each part: The main frame 1 of the drill frame consists of a main body plate 1.1, side plates 1.2, and a solenoid valve block mounting plate 1.3. The main body plate 1.1, while ensuring its load-bearing function, has been designed to be lightweight to reduce the overall weight of the drill frame. The side plates 1.2 are welded to the main body plate 1.1 to form an outer frame. The solenoid valve block mounting plate 1.3 is fastened to the main body plate 1.1, providing assembly space for the drill frame's solenoid valves. The anchor bolt chamber 2 is a rectangular frame formed by welding two lightweight horizontal plates 2.1 and two lightweight vertical plates 2.2 together. A locking mechanism 7 is designed and installed on it, which works in conjunction with the locking mechanism fixing block 5 installed on the main frame 1 of the drill frame to complete the locking and opening functions of the main frame 1 of the drill frame and the anchor bolt chamber 2.

[0029] like Figure 3 , 4As shown: The rotating shaft mechanism 6 includes a lubricating oil cup 6.1, a locking plate 6.2, an upper rotating plate 6.3, an intermediate shaft 6.4, a ball bearing plate 6.5, and a lower rotating plate 6.6; the upper rotating plate 6.3 and the lower rotating plate 6.6 are welded to the main frame 1 of the drill frame, and the ball bearing plate 6.5 is welded to the anchor bolt chamber 2; the intermediate shaft 6.4 passes through the shaft holes of the lower rotating plate 6.6, the ball bearing plate 6.5, and the upper rotating plate 6.3; the locking plate 6.2 and the intermediate shaft 6.4 are connected as a whole by threaded fastening; the ball bearing plate 6.5 meshes with the upper rotating plate 6.3 and the lower rotating plate 6.6; the lubricating oil cup 6.1 can lubricate the rotating shaft mechanism 6, ensuring the smooth and continuous rotation of the rotating shaft mechanism 6. The anchor bolt chamber 2 is driven to rotate by the rotation of the balls in the ball bearing plate 6.5. Due to the design of the double-layer ball bearing structure, if one layer gets stuck and cannot work, the rotating shaft mechanism 6 can still continue to be used, which enhances the operational reliability of the rotating shaft mechanism 6 and extends its service life.

[0030] like Figure 5 As shown: The locking mechanism 7 includes locking claws 7.1, a push-out switch 7.2, spring I 7.3, and spring II 7.4. There is one locking claw 7.1 at the top and one at the bottom. The middle of each locking claw 7.1 is hinged to the anchor bolt housing 2. Spring I 7.3 is installed between the two locking claws 7.1. Taking the hinge axis of the locking claws 7.1 as the boundary, spring I 7.3 is located on the side closer to the locking mechanism fixing block 5. A barb is provided on the outer side of the locking claw 7.1. Spring I 7.3 spreads the two locking claws 7.1 apart, causing the barbs of the locking claws 7.1 to engage around the hole. With the side of the locking claw 7.1 closest to the locking mechanism fixing block 5 as the head and the side farther from the locking mechanism fixing block 5 as the tail, the wedge-shaped structure of the head of the locking claw 7.1 extends to the barb, facilitating the convergence of the two locking claws 7.1 and their insertion into the hole. The tails of the two locking claws 7.1 are chamfered on the near side so that the push-out switch 7.2 can insert and pry open the two locking claws 7.1, and the barbs of the two locking claws 7.1 will close together and lose their locking function.

[0031] The locking mechanism fixing block 5 has a locking hole that mates with the locking claw 7.1.

[0032] The push-out switch 7.2 is located between the tails of the two locking claws 7.1. The head of the push-out switch 7.2 is pointed. The push-out switch 7.2 is slidably installed in the guide hole on the anchor bolt chamber 2. A spring II 7.4 is fitted on the push-out switch 7.2. One end of the spring II 7.4 abuts against the boss at the tail of the push-out switch 7.2, and the other end abuts against the anchor bolt chamber 2. The spring II 7.4 applies a thrust to the push-out switch 7.2 when it resets after unlocking the locking claws 7.1. The push-out switch 7.2 is provided with a limit ring, which stops at the anchor bolt chamber 2 and limits the stroke of the spring II 7.4 pushing the push-out switch 7.2.

[0033] When the drilling frame maintenance is completed, the anchor bolt chamber 2 can be closed directly. Under the action of external force, the locking claw 7.1 and the locking mechanism fixing block 5 come into contact with each other, causing the spring I7.3 to be compressed. The head of the locking claw 7.1 retracts into the locking hole of the locking mechanism fixing block 5. The locking mechanism 7 continues to move inward. When the locking claw 7.1 passes through the locking hole, the spring I7.3 springs up, and the locking claw 7.1 opens and mutually limits the locking mechanism fixing block 5, thus achieving locking.

[0034] When the drill frame needs maintenance, press the push-out switch 7.2. Under the action of external force, the head of the push-out switch 7.2 enters between the tails of the two locking claws 7.1. The tails of the two locking claws 7.1 are raised and the heads are closed, and the main frame 1 of the drill frame is separated from the anchor chamber 2, completing the opening and maintenance process. At the same time, under the action of spring II 7.4, the push-out switch 7.2 is pulled back and automatically reset.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
