Description

Technical Field

[0001] The utility model relates to the field of rock drilling jumbo, and more specifically, to an aluminum alloy guide rail for the propulsion beam of a rock drilling jumbo. Background Art

[0002] A rock drilling jumbo, also known as a drilling jumbo, is a rock drilling device used in tunneling and underground engineering construction using the drill and blast method. It can move and support multiple rock drills to carry out drilling operations simultaneously. The working mechanism mainly consists of a thruster, a drill boom, a slewing mechanism, and a translation mechanism. Rock drilling jumbos can be divided into drift jumbos, mining jumbos, bolt jumbos, and open-pit rock drilling jumbos, etc.; The drilling operation of a rock drilling jumbo requires a propulsion guide rail as the track for the reciprocating movement of drilling, and various auxiliary components such as a propulsion cylinder, a pipe follower, a drill rod holder, and an automatic drill rod changing mechanism are installed, which requires light weight, high strength, and low maintenance costs.

[0003] Some existing propulsion guide rails for rock drilling jumbos are integrally arranged. When a certain part of the propulsion guide rail is damaged, it is inconvenient to repair, and even the entire component needs to be replaced, resulting in waste of some materials. Therefore, in order to solve the above problems, we propose an aluminum alloy guide rail for the propulsion beam of a rock drilling jumbo. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides an aluminum alloy guide rail for the propulsion beam of a rock drilling jumbo, adopting the following technical scheme:

[0005] The aluminum alloy guide rail for the propulsion beam of a rock drilling jumbo includes a mounting plate. Four symmetrically distributed support rods are fixedly installed on one side of the mounting plate. A guide rail body is slidably installed between the four support rods, and the guide rail body is slidably sleeved on the side wall of the support rods. A baffle is slidably sleeved at one end of the four support rods away from the mounting plate, and screw threads are provided on the side walls of the four support rods away from the mounting plate. Nuts are sleeved on the side walls of the support rods, and a stabilizing component is provided between the four nuts and the baffle;

[0006] The guide rail body is composed of multiple support blocks arranged in parallel. Chutes are provided at the tops of the support blocks, and sliders are slidably installed in the chutes. Activity slots are provided on one side of the support blocks close to the mounting plate, and positioning components are provided in the activity slots;

[0007] Two symmetrically distributed support plates are fixedly installed on one side of the mounting plate close to the baffle, and both of the two support plates are located below the guide rail body. A plurality of connecting plates arranged in a linear array are fixedly installed between the two support plates.

[0008] By adopting the above technical solution, when the device is in use, the staff sleeved the support blocks on the side walls of the four support rods. The guide rail body is composed of a plurality of support blocks arranged in parallel, which is convenient for subsequent use. After the support blocks are installed, the staff placed the slider in the chute opened at the top of the support block. Subsequently, the baffle is sleeved on the side walls of the four support rods and screwed with the thread teeth opened on the side wall of the end of the support rod away from the mounting plate through the nut, which can play the role of screwing and positioning the support block. Subsequently, through the cooperation of the stabilizing component and the nut, the nut can be fixed, which helps to prevent the nut from loosening due to vibration during the use of the device and is beneficial to maintaining the stability of the splicing of the support blocks. The side wall of the support block is provided with a positioning component, which plays a positioning role and is beneficial to maintaining the accuracy of the fitting of two adjacent support blocks. The guide rail body is composed of a plurality of support blocks arranged in parallel and is then fixed by the support rods and nuts. When a certain support block is damaged, only the damaged support block needs to be replaced, and there is no need to replace the entire guide rail body, which reduces the waste of materials. The bottom of the guide rail body is provided with a support plate and a connecting plate, which play a role in supporting and stabilizing the guide rail body and are beneficial to maintaining the stability of the installation of the guide rail body.

[0009] Further, the stabilizing component includes a mounting block arranged on the side of the baffle away from the guide rail body. Both ends of the mounting block are fixedly installed with connecting blocks, and both ends of the two connecting blocks are fixedly installed with stabilizing rings. A groove matching the nut is opened inside the stabilizing ring. A bolt is arranged on the side of the mounting block away from the baffle, and one end of the bolt penetrates the mounting block. A screw groove matching the bolt is opened on the side of the baffle away from the guide rail body.

[0010] By adopting the above technical solution, after the guide rail body is installed, the staff makes the sides of the mounting block and the connecting block opposite to the baffle fit, and makes the stabilizing ring sleeved with the nut. Subsequently, the bolt passes through the mounting block and is screwed with the screw groove opened on the opposite side of the baffle, which can play the role of fixing and installing the stabilizing ring. By restricting the rotation of the nut through the stabilizing ring, it helps to prevent the nut from loosening due to vibration during the use of the device and is beneficial to maintaining the stability of the splicing of the support blocks.

[0011] Further, the positioning component includes a positioning rod slidably installed in the moving groove. A spring is fixedly connected between one end of the positioning rod away from the mounting plate and the inner wall of the opposite side of the same group of moving grooves. Positioning grooves matching the positioning rod are opened on the sides of the support block and the mounting plate close to the baffle.

[0012] By adopting the above technical scheme, when two adjacent support blocks are fitted together, the positioning rod engages with the positioning groove provided on the side wall of an adjacent support block. The engagement of the positioning rod and the positioning groove plays a role in positioning and stabilizing the support block, which is beneficial to maintaining the accuracy of splicing the two adjacent support blocks. When there is no positioning groove on the side wall of the installation location, the first support block fits with the installation location, the positioning rod slides into the same group of active grooves, and the positioning rod pushes the same group of springs to contract. The positioning rod can return to its original position under the elastic force of the same group of springs, which is convenient for subsequent use of the support block.

[0013] Furthermore, two symmetrically distributed limit blocks are fixedly mounted on the side wall of the positioning rod away from the mounting plate, and the inner wall of the movable groove is provided with a limit groove matching the limit blocks in the same group.

[0014] By adopting the above technical solution, when the positioning rod slides in the movable groove, the positioning rod slides in the limiting groove with the limiting block. The cooperation between the limiting block and the limiting groove is conducive to maintaining the sliding stability of the positioning rod and helps to prevent the positioning rod from leaving the movable groove.

[0015] Furthermore, a through hole is provided on the side wall of the mounting plate, and two symmetrically distributed limiting rods are fixedly mounted on one side of the mounting plate close to the baffle, and the two limiting rods at one end close to the baffle slide through the slider.

[0016] By adopting the above technical solution, the side wall of the mounting plate is provided with a through hole, which facilitates the existing push rod to pass through and connect with the side opposite to the slider. When the slider is located in the slide groove and slides, the slider slides onto the side wall of the limit rod. Through the setting of the limit rod, it plays a role in limiting and stabilizing the slider, which is beneficial to maintaining the stability of the slider sliding.

[0017] Furthermore, a card block is fixedly installed at the bottom end of the support block, and a card slot matching the card block of the same group is opened at the top end of the connecting block. A mounting rod is fixedly installed at one end of the mounting plate close to the baffle, and the mounting rod slides through the card block at one end away from the mounting plate, and a rubber sleeve is provided on the side wall of the mounting rod.

[0018] By adopting the above technical solution, when the support block is sleeved on the side wall of the support rod, the card block installed at the bottom end of the support block engages with the card slot opened at the top of the same group of connecting blocks, and the card block is slidably sleeved on the side wall of the mounting rod. Through the cooperation of the mounting rod, the card block and the card slot, the support block is supported and stabilized, which is beneficial to maintaining the stability of the installation of the guide rail body.

[0019] Furthermore, rubber pads are fixedly installed on both sides of the support block, and the side walls of the support rod at one end away from the mounting plate are sleeved with gaskets, and the gaskets are located between the nut and the baffle.

[0020] By adopting the above technical solution, rubber pads are provided on both sides of the support block. Pushed by the screwing of the nut with the thread teeth formed on the side wall of the support rod, the rubber pads can be squeezed, which is conducive to improving the sealing performance of the fit between the support blocks. The gasket provided on the side wall of the support rod is conducive to increasing the fastening force of the screwing between the nut and the support rod.

[0021] In summary, the present utility model has the following beneficial technical effects:

[0022] (1) In the present utility model, the guide rail body is composed of multiple support blocks arranged side by side, and is then fixed by the support rod and the nut.
