Description

Technical Field

[0001] This utility model relates to the field of anchor bolt trolley technology, and in particular to an oil pipe fixing structure for an anchor bolt trolley. Background Technology

[0002] An anchor bolt trolley is a self-moving piece of equipment used to drill anchor bolt holes in the roof or sidewalls of underground roadways and complete part or all of the anchor bolt installation process. It can complete the three processes of drilling, grouting and anchor bolt installation in sequence on one machine, realizing a high degree of mechanization and intelligence in anchor bolt support construction. It is widely used in anchor bolt support operations in mines, tunnel engineering and hydropower engineering to reinforce rocks. It is an important mining equipment, and its high degree of mechanization and intelligence provides reliable support for anchor bolt support operations in underground engineering.

[0003] Chinese patent document CN219101386U discloses an anchor bolt trolley that uses a sliding drive to move a scraper conveyor, a crusher, and a hopper. The front anchor bolter remains stationary on the anchor bolt trolley. Compared with the prior art, this allows the scraper conveyor to slide forward relative to the anchor bolt trolley to a suitable position with the main machine, while the front anchor bolter on the anchor bolt trolley remains stationary to continue fine support work. At this time, the main machine can cut and transport the next working face. After the main machine has cut the new working face and the fine support work in the anchor bolt trolley is completed, the main machine, the anchor bolt trolley, and the belt conveyor move forward together to the next working face. This achieves the effects of reducing equipment idle time, improving production efficiency, and saving mining costs.

[0004] However, in the existing anchor bolt trolleys, the oil pipes are often fixed to the anchor bolt arm with simple clips, which are loose and droopy. This makes it inconvenient to adjust the oil pipes to different fixing positions and can easily cause friction on the surface of the oil pipes. Utility Model Content

[0005] The main purpose of this utility model is to provide an oil pipe fixing structure for an anchor bolt trolley, which can effectively solve the problem of adjusting the oil pipe without changing its limiting position and easily causing wear on the oil pipe.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An oil pipe fixing structure for an anchor bolt trolley includes an anchor bolt mounting arm. A movable component is provided on the lower surface of the anchor bolt mounting arm. Limiting components are provided on both the left and right sides of the lower end of the movable component. Adjusting components are provided at the lower ends of the two limiting components. Four anti-wear components are provided on both sides of the two adjusting components.

[0008] Preferably, the movable component includes a fixed base, the upper surface of which is fixedly connected to the anchor rod mounting arm, and a bidirectional shaft motor is fixedly installed on the bottom wall of the inner cavity of the fixed base. Threaded rods are fixedly connected to the output ends on both sides of the bidirectional shaft motor, and the thread directions on the surfaces of the two threaded rods are opposite.

[0009] Preferably, the outer surfaces of both threaded rods are threaded with sliding blocks, and the rotation of the threaded rods can drive the two sliding blocks to move together in opposite directions. Sliding grooves are provided on both sides of the lower end of the fixed base, and the outer surfaces of the two sliding blocks are slidably connected to the two sliding grooves. Connecting blocks are fixedly connected to the lower ends of the two sliding blocks.

[0010] Preferably, the limiting component includes an annular sleeve, through which the oil pipe can be passed for limiting and fixing. The outer surface of the annular sleeve is fixedly connected to the connecting block. A bolt is threaded on one side of the annular sleeve, and one end of the bolt is rotatably connected to the limiting block. Rotating the bolt can push the limiting block to fix and limit the oil pipe. Movable grooves are provided on both the left and right sides of the annular sleeve.

[0011] Preferably, the adjusting component includes a fixed block, the upper end of which is fixedly connected to an annular sleeve. Limit seats are fixedly connected to both the upper and lower sides of the inner cavity of the fixed block. The limit seats can limit the sliding seat, allowing it to slide back and forth stably. Sliding seats are slidably connected to the outer surfaces of the two limit seats, which can drive the sliding sleeve to move outward or inward.

[0012] Preferably, both sliding seats are slidably connected to the fixed block, and the outer surfaces of both sliding seats are fixedly connected with serrations.

[0013] Preferably, a rotating block is rotatably connected inside the fixed block. Rotating the rotating block can drive the gear to rotate together. The gear is fixedly connected to the outer surface of the rotating block. The outer surfaces of the two saw teeth mesh with the gear. The rotation of the gear can drive the saw teeth on the upper and lower sides to move simultaneously in opposite directions. The upper ends of the two sliding seats are fixedly connected to sliding sleeves. The outer surface of the sliding sleeve is slidably connected to the movable groove. The sliding of the sliding sleeve can change the limiting range of the oil pipe and avoid wear on its surface over a long period of time.

[0014] Preferably, the anti-wear component includes a spring, one end of which is fixedly connected to the inner wall of the sliding sleeve, and the end of the spring away from the sliding sleeve is fixedly connected to an anti-friction roller, which helps the oil pipe slide back and forth without causing wear on its surface.

[0015] Compared with the prior art, the present invention has the following advantages: by setting movable components and limiting components at the lower end of the anchor rod mounting arm, the oil pipes at different positions can be fixed, which is convenient to adapt to different working environments. At the same time, the limiting area of ​​the oil pipes can be expanded or reduced by using the adjusting components and anti-wear components, avoiding wear caused by staying in one position for a long time, thus improving the practicality of the device.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, an oil pipe fixing structure for an anchor bolt trolley includes an anchor bolt mounting arm 1. A movable component 2 is provided on the lower surface of the anchor bolt mounting arm 1. The anchor bolt mounting arm 1 is a prior art technology. It mainly achieves accurate connection between the tensioning element and the anchor bolt through a first power mechanism, a second power mechanism applies prestress to the anchor bolt, and a third power mechanism drives a locking element to lock the fastening nut, ultimately ensuring that the anchor bolt has stable support and fixing capacity in underground engineering. Limiting components 3 are provided on both the left and right sides of the lower end of the movable component 2. Adjusting components 4 are provided at the lower ends of the two limiting components 3. Four anti-wear components 5 are provided on both sides of the two adjusting components 4.

[0024] The active component 2 includes a fixed base 201, the upper surface of which is fixedly connected to the anchor rod mounting arm 1. A bidirectional shaft motor 202 is fixedly installed on the bottom wall of the inner cavity of the fixed base 201. Threaded rods 203 are fixedly connected to the output ends on both sides of the bidirectional shaft motor 202. The threads on the surfaces of the two threaded rods 203 are in opposite directions.

[0025] The outer surfaces of the two threaded rods 203 are threaded with sliding blocks 204. Rotation of the threaded rods 203 can drive the two sliding blocks 204 to move together in opposite directions. Sliding grooves 205 are provided on both sides of the lower end of the fixed base 201. The outer surfaces of the two sliding blocks 204 are slidably connected to the two sliding grooves 205. The lower ends of the two sliding blocks 204 are fixedly connected with connecting blocks 206.

[0026] The limiting component 3 includes an annular sleeve 301, through which the oil pipe can be limited and fixed. The outer surface of the annular sleeve 301 is fixedly connected to the connecting block 206. A bolt 302 is threadedly connected to one side of the annular sleeve 301. One end of the bolt 302 is rotatably connected to the limiting block 303. Rotating the bolt 302 can push the limiting block 303 to fix and limit the oil pipe. Movable grooves 304 are provided on both the left and right sides of the annular sleeve 301.

[0027] The adjusting component 4 includes a fixing block 401. The upper end of the fixing block 401 is fixedly connected to the annular sleeve 301. Limiting seats 402 are fixedly connected to both the upper and lower sides of the inner cavity of the fixing block 401. The limiting seats 402 can limit the sliding seat 403, so that it can slide back and forth stably. The outer surfaces of the two limiting seats 402 are slidably connected to the sliding seat 403, which can drive the sliding sleeve 407 to move outward or inward.

[0028] Both sliding seats 403 are slidably connected to the fixed block 401, and the outer surfaces of both sliding seats 403 are fixedly connected with serrations 404.

[0029] The fixed block 401 is rotatably connected to a rotating block 405. Rotating the rotating block 405 can drive the gear 406 to rotate together. The gear 406 is fixedly connected to the outer surface of the rotating block 405. The outer surfaces of the two saw teeth 404 mesh with the gear 406. Rotating the gear 406 can drive the saw teeth 404 on the upper and lower sides to move in opposite directions at the same time. The upper ends of the two sliding seats 403 are fixedly connected to sliding sleeves 407. The outer surface of the sliding sleeves 407 is slidably connected to the movable groove 304. The sliding of the sliding sleeves 407 can change the limiting range of the oil pipe and avoid wear on its surface over a long period of time.

[0030] The anti-wear component 5 includes a spring 501, one end of which is fixedly connected to the inner wall of the sliding sleeve 407. The end of the spring 501 away from the sliding sleeve 407 is fixedly connected to an anti-friction roller 502, which helps the oil pipe slide back and forth without causing wear on its surface.

[0031] It should be noted that the specific installation method, circuit connection method, and control method of the anchor rod mounting arm 1 and the bidirectional shaft motor 202 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0032] The working principle of this utility model is as follows: When fixing the position of the oil pipe, start the bidirectional shaft motor 202 to drive the threaded rod 203 to rotate, so that the sliding block 204 drives the two connecting blocks 206 to move in opposite directions, thereby driving the two sets of limiting components 3 to move together to different positions of the oil pipe. Then, rotate the bolt 302 to push the limiting block 303 to limit the oil pipe. When the surface of the oil pipe is worn due to long-term fixation, the rotating block 405 can be twisted to drive the gear 406 to rotate, so that the sliding seats 403 on the upper and lower sides of the gear 406 move outward at the same time, driving the sliding sleeve 407 to move outward from the annular sleeve 301, thereby expanding or changing the limiting range of the oil pipe.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
