Description

Technical Field

[0001] The utility model relates to the technical field of propulsion beam cutting production, in particular to a propulsion beam positioning tool. Background Art

[0002] In mining engineering and similar fields, rock drills are usually used to perform drilling and blasting construction on tunnels, mines or underground projects. Such rock drills are also called drilling trolleys. The rock drill trolleys include rock drill propulsion beams, which include propulsion beam bodies, rock drills, drill rods, drill bits and other components. When the rock drill trolley is working, the drill rod moves under the control of the impact mechanism and drill rotation mechanism, and at the same time drives the drill bit to rotate and impact continuously, so that the drill bit continuously impacts the rock according to the design requirements, and at the same time uses the powder discharge mechanism to discharge stone chips, thereby drilling blast holes. It is very convenient and fast, and can be widely used in the drilling of various holes.

[0003] Publication number CN 107724958 A discloses a rock drilling trolley propulsion beam, including a propulsion beam body, on which a gyroscope for detecting the inclination angle in the vertical direction and an angle encoder for detecting the inclination angle in the horizontal plane are provided, the angle encoder is arranged at the horizontal rotation center of the propulsion beam body, and the angle encoder and the gyroscope are electrically connected to the controller respectively. In this rock drilling trolley propulsion beam, the angle measured by the gyroscope is the angle with the earth's gravity, which has nothing to do with the slope where the vehicle body is placed, and its measurement result is not affected by the placement of the vehicle body, so that the angle of the propulsion beam body in the vertical direction can be directly measured, the accuracy of the angle measurement can be improved, and the certainty of the propulsion beam in any direction can be guaranteed, thereby ensuring the accuracy of the drilling direction of the propulsion beam and improving the quality of rock blasting. The invention also discloses a rock drilling trolley including the above-mentioned rock drilling trolley propulsion beam, which can improve the accuracy of angle measurement.

[0004] However, the push beam has the following shortcomings: the push beam needs to be cut during production and processing, but often due to the lack of a positioning mechanism that matches the size of the push beam during cutting, it shakes during cutting, causing the cutting position to shift, affecting the cutting accuracy.

[0005] Therefore, the utility model provides a propulsion beam positioning tool to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a propulsion beam positioning tool to solve the above problems.

[0007] To achieve the above object, the utility model is realized by the following technical solutions: A positioning tooling for a propulsion beam, including a placement base, a cutting table is fixedly connected to the top of the placement base, and two mounting boxes are fixedly connected to the top of the placement base. Positioning mechanisms are provided on both mounting boxes;

[0008] The positioning mechanism includes a U-shaped bracket fixedly connected to the outer wall of the mounting box. A fixed box is penetrated through the U-shaped bracket. Two threaded long rods are rotatably connected in the fixed box. L-shaped connecting plates are threadedly sleeved on both threaded long rods. The bottom ends of the two L-shaped connecting plates both slide and extend outside the fixed box. The bottom ends of the two L-shaped connecting plates are fixedly connected to the same upper pressing plate. Four bidirectional threaded rods are rotatably connected in the mounting box. Two symmetrically distributed side clamping plates are threadedly sleeved on each of the four bidirectional threaded rods. The top of the side clamping plate slides and extends outside the mounting box.

[0009] Preferably, double-row synchronous pulleys are fixedly sleeved on the corresponding four bidirectional threaded rods. The same first synchronous belt is wound between every two adjacent double-row synchronous pulleys. Single-row synchronous pulleys are fixedly sleeved on the corresponding four bidirectional threaded rods. A second synchronous belt is wound on the single-row synchronous pulley. One side of the second synchronous belt is wound on the corresponding double-row synchronous pulley. The combined use of the double-row synchronous pulleys, the first synchronous belt, the single-row synchronous pulleys and the second synchronous belt can facilitate the synchronous rotation of the four bidirectional threaded rods.

[0010] Preferably, driven gears are fixedly sleeved on the corresponding two bidirectional threaded rods. First motors are fixedly connected in both mounting boxes. The output shaft of the first motor is fixedly connected with a driving gear. The driving gear meshes with the driven gear. The combined use of the driven gear, the first motor and the driving gear can facilitate the rotation of the connected bidirectional threaded rod.

[0011] Preferably, linkage gears are fixedly sleeved on both threaded long rods. A second motor is fixedly connected to the top of the fixed box. The output shaft of the second motor is fixedly connected with a transmission shaft. The bottom end of the transmission shaft rotates and extends into the fixed box. A driving gear is fixedly sleeved on the transmission shaft. The driving gear meshes with both linkage gears. The combined use of the linkage gear, the second motor, the transmission shaft and the driving gear can facilitate the synchronous rotation of the two threaded long rods.

[0012] Preferably, a side plate is fixedly connected to one side of the side clamping plate. A plurality of sliding rods are fixedly connected in the mounting box. The sliding rods slidably penetrate through the corresponding side clamping plates. The combined use of the side plate and the sliding rods can facilitate the limitation of the side clamping plate and make its movement smooth.

[0013] Preferably, two positioning rods are fixedly connected in the fixed box, and the two positioning rods slide through the corresponding L-shaped connecting plates respectively. A limit plate is fixedly sleeved on the positioning rods. The L-shaped connecting plate can be limited by using the positioning rods and the limit plate in combination, making its movement smoother.

[0014] Preferably, a first soft pad is fixedly connected to the bottom of the upper pressure plate, and a second soft pad is fixedly connected to one side of the side clamping plate. The first and second soft pads can increase the contact friction between the upper pressure plate, the side clamping plate and the thrust beam, making it easier to clamp them while avoiding scratches and wear, resulting in a better use effect.
