Description

Technical Field

[0001] This utility model belongs to the field of rock drill technology, specifically relating to a wheeled walking structure for a rock drill with a shock absorption and buffer device. Background Technology

[0002] The wheeled walking structure of a rock drill is a crucial component for its mobility. The frame serves as the basic framework, supporting and connecting other components such as the engine, cab, and drill arm. It is typically welded from high-strength steel, possessing sufficient strength and rigidity to withstand the various forces generated during operation. The wheels generally use solid or pneumatic tires. Solid tires offer high wear resistance and load-bearing capacity, suitable for harsh working environments; pneumatic tires provide better shock absorption and ride comfort, adapting to different road conditions. The wheels are connected to the axle via hubs, and the axle is mounted on the frame. The drive system provides power to the rock drill's wheeled walking structure, enabling it to move. The drive system typically consists of an engine, transmission, drive shaft, differential, and drive wheels. The engine's power output is changed in speed and torque by the transmission, then transmitted to the differential via the drive shaft. The differential distributes power to the left and right drive wheels, causing them to rotate and enabling the rock drill to move.

[0003] Currently, existing rock drill wheel-type walking structures typically use motors to drive the wheels and move the rock drill. However, during the movement of a traditional rock drill wheel-type walking structure, the front end of the rock drill may collide with objects. Since the front end of the rock drill wheel-type walking structure does not have a good buffer structure, the collision with objects may damage the rock drill, thereby increasing the maintenance cost of the rock drill. Utility Model Content

[0004] The purpose of this utility model is to provide a rock drill wheel-type walking structure with a shock absorption and buffer device. It aims to solve the problem that in the existing rock drill wheel-type walking structures, the rock drill is usually driven by a motor to move the wheels. However, in the traditional rock drill wheel-type walking structure, the front end of the rock drill may collide with objects during the movement. Since the front end of the rock drill wheel-type walking structure does not have a good buffer structure, the collision with the object may damage the rock drill, thereby increasing the maintenance cost of the rock drill.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rock drill wheel-type walking structure with shock absorption and buffer device, including a rock drill frame, rock drill wheels installed on both sides of the rock drill frame, wheel baffles installed on both sides of the rock drill frame, a front frame installed at one end of the rock drill frame, and a connecting seat installed on the outer wall of the front frame.

[0006] A mounting bracket is fixedly connected to the back of the connecting seat. Two fixing blocks are fixedly connected inside the connecting seat. The outer walls of the two mounting brackets are provided with mounting grooves. A damper is installed on the inner side of the mounting groove. A guide rod is fixedly connected between the two fixing blocks. A buffer spring is sleeved on the end of the guide rod. One end of the buffer spring is connected to a movable block. A rotating rod is rotatably connected to the outer wall of the movable block. A connecting plate is rotatably connected to the end of the rotating rod away from the movable block. A buffer layer is connected to the surface of the connecting plate.

[0007] As a preferred embodiment of the rock drill wheel-type walking structure with shock absorption and buffer device of this utility model, two movable blocks are symmetrically distributed, and the two movable blocks are sleeved on the outer wall of the guide rod.

[0008] As a preferred embodiment of the rock drill wheel-type walking structure with shock absorption and buffer device of this utility model, the fixed block can form an elastic structure with the fixed block through the guide rod and the buffer spring.

[0009] As a preferred embodiment of the rock drill wheel-type walking structure with shock absorption and buffer device of this utility model, two dampers are provided, and the two dampers are symmetrically distributed at both ends of the connecting plate.

[0010] As a preferred embodiment of the rock drill wheel-type walking structure with shock absorption and buffer device of this utility model, the buffer layer is made of styrene-based thermoplastic elastomer.

[0011] As a preferred embodiment of the rock drill wheel-type walking structure with shock absorption and buffer device of this utility model, the mounting frame is C-shaped, and the front frame is located inside the mounting frame.

[0012] As a preferred embodiment of the rock drill wheel-type walking structure with shock absorption and buffer device of this utility model, the mounting frame has mounting holes at both the top and bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The connecting seat is fixedly installed on the front frame of the vehicle by the mounting bracket. When the front end of the rock drill's wheeled walking structure collides with an object, the buffer layer made of styrene-based thermoplastic elastomer can play a certain buffering role after contact with the object. Together with the dampers at both ends of the inner side of the connecting seat, it can play a shock absorption role. After the buffer layer is stressed, the connecting plate will move backward, causing the two rotating rods on the back of the connecting plate to rotate. The rotation of the rotating rods can drive the two movable blocks to move in opposite directions along the guide rod. At the same time, the two moving movable blocks in opposite directions will compress the buffer spring and deform it, thereby absorbing and reducing the impact and vibration of the rock drill during the movement, further improving the shock absorption and buffering effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a rock drill wheel walking structure with shock absorption and buffer device, including a rock drill frame 1, rock drill wheels 2 installed on both sides of the rock drill frame 1, wheel baffles 3 installed on both sides of the rock drill frame 1, a front frame 4 installed at one end of the rock drill frame 1, and a connecting seat 5 installed on the outer wall of the front frame 4.

[0023] It should be noted that the rock drill wheels 2 are driven by an electric motor to move the rock drill frame 1.

[0024] A mounting bracket 6 is fixedly connected to the back of the connecting seat 5. Two fixing blocks 7 are fixedly connected inside the connecting seat 5. The outer walls of the two mounting brackets 6 are provided with mounting grooves 8. A damper 9 is installed on the inner side of the mounting grooves 8. A guide rod 10 is fixedly connected between the two fixing blocks 7. A buffer spring 11 is sleeved at the end of the guide rod 10. A movable block 12 is connected to one end of the buffer spring 11. A rotating rod 13 is rotatably connected to the outer wall of the movable block 12. A connecting plate 14 is rotatably connected to the end of the rotating rod 13 away from the movable block 12. A buffer layer 15 is connected to the surface of the connecting plate 14.

[0025] Preferably, there are two movable blocks 12 symmetrically distributed, and the two movable blocks 12 are sleeved on the outer wall of the guide rod 10. The fixed block 7 can form an elastic structure with the fixed block 7 through the guide rod 10 and the buffer spring 11. There are two dampers 9, and the two dampers 9 are symmetrically distributed at both ends of the connecting plate 14. The buffer layer 15 is made of styrene thermoplastic elastomer.

[0026] In practical use, the connecting seat 5 is fixedly installed on the front frame 4 of the vehicle by the mounting bracket 6. When the front end of the rock drill's wheeled walking structure collides with an object, the buffer layer 15 made of styrene-based thermoplastic elastomer can play a certain buffering role after contacting the object. Together with the dampers 9 at both ends of the inner side of the connecting seat 5, it can play a shock absorption effect. After the buffer layer 15 is subjected to force, the connecting plate 14 will move backward, causing the two rotating rods 13 on the back of the connecting plate 14 to rotate. The rotating rods 13 can drive the two movable blocks 12 to move in opposite directions along the guide rod 10. At the same time, the two moving movable blocks 12 will squeeze the buffer spring 11 to deform it, thereby absorbing and reducing the impact and vibration of the rock drill during the walking process, further improving the shock absorption and buffering effect.

[0027] It should be noted that the buffer layer 15, made of styrene-based thermoplastic elastomer, combines the elasticity of rubber with the processability of plastic. It is wear-resistant, tear-resistant, and can recover its original shape after multiple impacts. The buffer spring 11 is made of alloy spring steel.

[0028] Preferably, the mounting bracket 6 is C-shaped, and the front frame 4 is located inside the mounting bracket 6. Mounting holes 16 are provided at the top and bottom of the mounting bracket 6.

[0029] In practical use, the shock absorber can be installed and fixed by fitting the “C”-shaped mounting bracket 6 onto the front frame 4 and then connecting the bolts through the mounting holes 16 to the holes on the front frame 4.

[0030] It should be noted that the outer wall of the front frame 4 has threaded holes that match the position and number of mounting holes 16.

[0031] Working principle: First, the "C"-shaped mounting bracket 6 is placed on the front frame 4. Then, the shock-absorbing buffer device is installed and fixed by connecting the bolts through the mounting holes 16 and the holes on the front frame 4. When the front end of the rock drill's wheeled walking structure collides with an object, the buffer layer 15 made of styrene-based thermoplastic elastomer can play a certain buffering role after contact with the object. Together with the dampers 9 at both ends of the inner side of the connecting seat 5, it can play a shock-absorbing role. After the buffer layer 15 is subjected to force, the connecting plate 14 will move backward, causing the two rotating rods 13 on the back of the connecting plate 14 to rotate. The rotating rods 13 can drive the two movable blocks 12 to move in opposite directions along the guide rod 10. At the same time, the two moving movable blocks 12 will squeeze the buffer spring 11 to deform it, thereby absorbing and reducing the impact and vibration of the rock drill during the movement, further improving the shock absorption effect.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
