Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mining machinery, and concretely relates to a height-adjustable chassis device and drilling equipment. BACKGROUND

[0002] In the field of mining machinery, the raise drill is a key equipment for underground mining and construction, and the design of the chassis device thereof is crucial to adapt to variable and complex terrain conditions. However, the existing chassis device of the raise drilling equipment has a small departure angle and approach angle of the vehicle head and cannot be adjusted when walking, resulting in poor passability in complex road conditions.

[0003] For example, the balance beam crawler chassis disclosed in Chinese patent document CN112455562A falls in a fixed position when the walking power component connected to the other end of the balance beam assembly falls after the main machine of the drill is lifted by the balance beam assembly.

[0004] This structure has insufficient height adjustment flexibility of the walking power component when facing rugged road conditions, ups and downs, and construction environments with many obstacles, resulting in inability to provide effective obstacle avoidance capability, easy to cause equipment damage or downtime, and affect engineering efficiency. SUMMARY

[0005] Therefore, the utility model provides a height-adjustable chassis device and drilling equipment to solve the problem that the existing chassis device cannot flexibly adjust the height of the walking power component.

[0006] The utility model provides a height-adjustable chassis device, comprising: a front beam seat for mounting on a walking device; a rear base rotatably connected with the front beam seat, one end of the rear base extending away from the front beam seat and used for connecting with a power component of the walking device; a first adjustment driving member connected with the rear base, the first adjustment driving member being used for driving the rear base to rotate relative to the front beam seat.

[0007] Through the above setting, the front beam seat is installed on the walking device to provide a stable support point for the whole chassis device, ensuring the base stability of the device when running. The rear base is rotationally connected with the front beam seat, and one end is connected with the power component of the walking device. This connection mode provides a basis for the height adjustment of the power component. Under the action of the first adjusting drive, when the rear base is driven to rotate relative to the front beam seat, the height of the power component will also change. In the complex mine operation environment, when encountering uneven road surfaces or obstacles, the chassis device of the prior art has poor passability due to the fixed height of the power component. The design of the utility model can flexibly adjust the height of the power component with the help of the first adjusting drive, thereby increasing the departure angle and approach angle of the vehicle head, so that the drilling equipment can easily cross obstacles and smoothly pass through complex road conditions.

[0008] Optionally, the first adjusting drive has at least two arranged side by side.

[0009] Through the above setting, at least two first adjusting drives arranged side by side can significantly enhance the stability of the rotation adjustment of the rear base. When one of the drives is disturbed by the outside world or has a slight deviation during operation, the other drives can play a cooperative correction role to ensure that the rotation of the rear base always remains on the predetermined track, avoiding shaking or deviation.

[0010] Optionally, the first adjusting drive is a linear telescopic drive structure, one end of the first adjusting drive is connected with the rear base, and the other end of the first adjusting drive is connected with the front beam seat.

[0011] Through the above setting, one end of the linear telescopic drive structure is connected with the rear base, and the other end is connected with the front beam seat, thereby constructing a direct and stable force transmission path. When the first adjusting drive works, its linear telescopic action can be converted into the rotation of the rear base relative to the front beam seat. The stroke of the linear telescopic drive structure is easy to accurately control, and the operator can accurately adjust the rotation angle of the rear base by controlling the telescopic length of the drive according to actual needs, thereby ensuring that the chassis height can meet the requirements of various complex working conditions and providing a strong guarantee for the stable operation of the drilling equipment in different environments.

[0012] Optionally, the connection positions of the first adjusting drive with the rear base and the front beam seat are located above the rotation connection position of the rear base and the front beam seat; and one end of the first adjusting drive connected with the rear base is higher than the other end of the first adjusting drive connected with the front beam seat.

[0013] Through the above setting, since the connection positions are all higher than the rotation connection point, when the first adjusting driving member is extended or retracted, a greater force arm can act on the rear base, and under the same driving force, a greater torque can be generated, so that the rotation of the rear base relative to the front beam seat is more relaxed and efficient, thereby realizing rapid adjustment of the height of the power component. Secondly, the stability can be effectively improved during the adjustment process. The higher connection point makes the force distribution of the rear base more uniform during rotation, reduces the shaking or jamming phenomenon caused by uneven force, and ensures the stability of the adjustment action, so that the adjustment of the chassis height is more accurate and reliable.

[0014] Optionally, one end of the front beam seat extends away from the rear base and is used for connecting with the drilling machine.

[0015] Through the above setting, a stable support foundation is provided for the drilling machine in structure. The extension design increases the connection span of the drilling machine and the chassis, disperses the pressure and vibration generated by the drilling machine during operation, enhances the stability of the entire device, avoids shaking or displacement of the drilling machine due to unstable connection, and ensures the operation accuracy.

[0016] The utility model also provides a kind of drilling equipment, comprising: travelling device, power component and drilling machine, height-adjustable chassis device is installed on the travelling device, the power component and the drilling machine are connected on the chassis device respectively.

[0017] Through the above setting, the height-adjustable chassis device is above the travelling device, effectively integrates the power component and the drilling machine, makes the space utilization between components more compact, avoids the problems such as too large volume and loose structure of the drilling equipment caused by dispersed components, facilitates the transportation and installation of the equipment. The power component and the drilling machine connected on the chassis device can maintain high degree of cooperation during operation. When different operation requirements are encountered, the chassis device adjusts height flexibly, ensures stable operation of the drilling machine, improves operation accuracy, enhances the reliability of the equipment, and improves the continuous operation capability of the drilling equipment.

[0018] Optionally, the travelling device has a driving shaft, and the front beam seat is rotationally connected to the driving shaft.

[0019] Through the above setting, the front beam seat is rotationally connected to the driving shaft of the travelling device, which improves the cooperative flexibility between the chassis device and the travelling device, so that the chassis device can flexibly change its angle according to the actual road conditions. When the drilling equipment turns, the front beam seat can rotate relative to the driving shaft to help adjust the walking direction, reduce the turning radius, and improve the maneuverability of the drilling equipment in narrow space. The power of the travelling device is more directly and efficiently transmitted to the front beam seat through the driving shaft, thereby driving the rear base, power component and drilling machine connected thereto to operate cooperatively, reducing power loss and improving the overall power transmission efficiency and work efficiency of the drilling equipment.

[0020] Optionally, the second adjustment driving member is further configured to drive the front beam seat to rotate relative to the walking device.

[0021] Through the above arrangement, the second adjustment driving member can accurately drive the front beam seat to rotate relative to the walking device, thereby driving the drilling rig to realize the switching of the working state. When the drilling equipment faces complex and variable terrain, the angle of the front beam seat can be quickly adjusted according to the actual situation. When the working posture of the drilling equipment needs to be adjusted, such as adjusting the angle or direction of the drilling hole, the second adjustment driving member can drive the entire chassis device and the power components and the drilling rig connected thereto to be adjusted in angle by controlling the rotation of the front beam seat, without the need to move the position of the drilling equipment as a whole, so as to realize the fine adjustment of the working position and angle, and improve the accuracy and efficiency of the work.

[0022] Optionally, the second adjustment driving member has at least two symmetrically arranged.

[0023] Through the above arrangement, the stability and balance of the driving of the front beam seat relative to the walking device are improved. The symmetrically distributed driving members can uniformly apply force to the front beam seat, avoiding problems such as rotation jamming, tilting or deviation of the front beam seat due to uneven force. During the driving of the front beam seat, the driving members can work cooperatively to accurately control the angle and speed of rotation, achieving more accurate adjustment effect.

[0024] Optionally, the second adjustment driving member is a linear extension driving structure, one end of the second adjustment driving member is connected with the front beam seat, and the other end of the second adjustment driving member is connected with the walking device; the connection position of the second adjustment driving member with the front beam seat is higher than the connection position of the second adjustment driving member with the walking device, and the connection position of the second adjustment driving member with the front beam seat is higher than the driving shaft.

[0025] Through the above arrangement, the linear extension driving structure of the second adjustment driving member cooperates with the specific connection position to produce good mechanical effect. Since one end of the second adjustment driving member is connected with the front beam seat and the connection position is higher than the connection position with the walking device and also higher than the driving shaft, a smaller extension stroke can realize a larger angle rotation of the front beam seat relative to the walking device, greatly improving the adjustment efficiency. Moreover, during the adjustment process, the force can be more uniformly distributed on the front beam seat, avoiding local excessive force leading to structural damage, prolonging the service life of the front beam seat and the entire connection structure.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0035] The following will describe the embodiments of the present application in combination with Figures 1 to 5

[0036] As shown in Figure 1 , one specific embodiment of the height-adjustable chassis device provided by the embodiments of the present application comprises: a front beam seat 1, a rear base 2 and a first adjustment driving member 3. ​

[0037] Specifically, the front beam seat 1 is used to be mounted on the traveling device 5; the rear base 2 is rotatably connected to the front beam seat 1, and one end of the rear base 2 extends away from the front beam seat 1 and is used to connect to the power component 6 of the traveling device 5. The traveling device 5 is generally a track, and the power component 6 is generally an engine in the front of the vehicle; the first adjustment drive 3 is connected to the rear base 2, and the first adjustment drive 3 is used to drive the rear base 2 to rotate relative to the front beam seat 1, thereby driving the front of the vehicle where the power component 6 is located to swing up and down through the rear base 2.

[0038] In this embodiment, the front beam seat 1 is securely connected to the walking device 5, providing a reliable foundation support for the entire chassis device. This ensures that the chassis will not shake or shift during the operation of the drilling equipment, guaranteeing the stability of the equipment. The rotatable connection between the rear base 2 and the front beam seat 1, as well as its connection to the power component 6, creates a flexible mechanical structure. The first adjustment drive 3 can precisely drive the rear base 2 to rotate relative to the front beam seat 1, allowing for flexible adjustment of the height of the power component 6. This enhances the adaptability of the chassis device. In complex construction environments, such as encountering uneven roads, steep slopes, or obstacles, operators can quickly adjust the height of the power component 6 using the first adjustment drive 3, increasing the departure and approach angles of the vehicle. This allows the drilling equipment to smoothly cross obstacles and navigate various complex road conditions, significantly improving the drilling equipment's passability and obstacle avoidance capabilities. This solves the problem of poor passability caused by the inability of traditional chassis devices to flexibly adjust the height of the power component 6.

[0039] like Figure 2 As shown, this is a specific embodiment of the height-adjustable chassis device provided in this embodiment, wherein the first adjustment drive 3 has at least two arranged in parallel.

[0040] Specifically, at least two parallel first adjustment drive components 3 significantly improve the adjustment performance of the entire chassis system. The simultaneous operation of multiple drive components provides a stronger driving force. When the height of the power unit 6 needs to be quickly adjusted to cope with complex road conditions, the adjustment time is shortened, and the response speed of the chassis system is improved. From a stability perspective, when one drive component experiences a slight deviation due to external factors, the other parallel drive components can compensate in time, ensuring smooth and stable rotation of the rear base 2 relative to the front beam seat 1, avoiding wobbling or offset, and effectively enhancing the stability of the adjustment process.

[0041] like Figure 2As shown, this is a specific implementation of the height-adjustable chassis device provided in this embodiment. The first adjustment drive 3 is a linear telescopic drive structure. One end of the first adjustment drive 3 is connected to the rear base 2, and the other end of the first adjustment drive 3 is connected to the front beam seat 1.

[0042] Specifically, the first adjustment drive component 3 adopts a linear telescopic drive structure, which has high power transmission efficiency and minimal energy loss, ensuring high efficiency in the adjustment process. One end connects to the rear base 2, and the other end connects to the front beam seat 1, ensuring that force is applied evenly and continuously between the rear base 2 and the front beam seat 1 during adjustment. The linear telescopic drive structure facilitates precise control of the telescopic length, thereby accurately regulating the rotation angle of the rear base 2 relative to the front beam seat 1, achieving fine-tuning of the height of the power component 6. This improves the stability and reliability of the chassis device during adjustment, ensuring efficient operation of the drilling equipment under complex working conditions.

[0043] Furthermore, two ear plates 4 are spaced apart at the positions where the rear base 2 and the front beam seat 1 connect to the first adjusting drive component 3. A space for placing the connecting block is formed between the two ear plates 4. The ear plates 4 have mounting through holes, which enhances the stability of the connection. The connecting block is placed in the space formed by the ear plates 4, and is fastened to the first adjusting drive component 3 by bolts or other connecting parts through the mounting through holes. This can effectively disperse the force generated when the first adjusting drive component 3 extends and retracts, and avoid loosening or damage to the connection due to excessive local stress. This ensures that the connection between the rear base 2 and the front beam seat 1 is always firm and reliable during the operation of the drilling equipment, and guarantees the stability of the height adjustment of the power component 6.

[0044] like Figure 4 As shown, this is a specific embodiment of the height-adjustable chassis device provided in this embodiment. The connection positions of the first adjustment drive 3 with the rear base 2 and the front beam seat 1 are both located above the position where the rear base 2 and the front beam seat 1 are rotatably connected; the end of the first adjustment drive 3 connected to the rear base 2 is higher than the end of the first adjustment drive 3 connected to the front beam seat 1.

[0045] Specifically, the connection positions of the first adjusting driving member 3 with the rear base 2 and the front beam seat 1 are all higher than the rotation connection points of the rear base 2 and the front beam seat 1, and the end connected with the rear base 2 is higher, so that the driving member directly and effectively drives the rear base 2 to rotate relative to the front beam seat 1 during extension and contraction. When adjusting the height of the power component 6, a small extension and contraction amount can achieve a significant height change, and the adjustment efficiency is greatly improved. The force action is more uniform and stable. During the adjustment process, the relative rotation between the rear base 2 and the front beam seat 1 is more stable, and there is no shaking or deviation, which meets the high-precision adjustment requirements under different working conditions. The structural strength of the entire chassis device is enhanced. When the drilling equipment operates in complex road conditions, it can better disperse and withstand forces from all directions, reducing the risk of structural deformation or damage, providing a solid guarantee for stable and reliable operation of the drilling equipment, and ensuring efficient operation of the drilling equipment in various harsh environments.

[0046] As shown in Figure 4 , it is a specific embodiment of the height-adjustable chassis device provided in the embodiment, and one end of the front beam seat 1 extends away from the rear base 2 and is used for connecting with the drilling machine.

[0047] Specifically, the extended front beam seat 1 provides a wider and more stable mounting base for the drilling machine, effectively disperses the pressure and vibration generated by the drilling machine during operation, avoids connection loosening or component damage caused by uneven local stress, ensures that the drilling machine always remains stable during operation, and improves its operation accuracy. Shortens the power transmission distance between the drilling machine and other parts of the chassis, so that power can be quickly and efficiently transmitted from the walking device 5 to the drilling machine through the chassis, improving the collaborative operation capability between the parts of the drilling equipment, and thus improving the overall work efficiency.

[0048] As shown in Figure 5 , it is a specific embodiment of the drilling equipment provided in the embodiment, which comprises a walking device 5, a power component 6 and a drilling machine, the walking device 5 is provided with a height-adjustable chassis device, and the power component 6 and the drilling machine are connected to the chassis device respectively.

[0049] Specifically, the walking device 5 is equipped with a height-adjustable chassis device, which provides a stable and flexible moving foundation for the entire drilling equipment. When the drilling equipment operates in different construction sites, the height-adjustable chassis device can quickly adjust its height according to the terrain conditions, ensure the stable movement of the walking device 5, create good conditions for the stable output of power of the power component 6, and at the same time ensure that the drilling machine can accurately position and efficiently operate in various complex environments. The collaborative capability between the components of the drilling equipment is enhanced, and the adaptability of the drilling equipment under different working conditions is significantly improved, which not only improves the operation efficiency, but also ensures the engineering quality, effectively solving the problems of low operation efficiency and poor stability of traditional drilling equipment in complex terrain.

[0050] As Figure 3 shown, a specific embodiment of the height-adjustable chassis device provided in the embodiment has a drive shaft 7 on the walking device 5, and the front beam seat 1 is rotationally connected to the drive shaft 7.

[0051] Specifically, the drive shaft 7 realizes the connection between the walking devices 5 on both sides of the drilling equipment and between the walking device 5 and the front beam seat 1, reduces the energy loss in the power transmission process during the movement of the drilling equipment, improves the power transmission efficiency, and ensures that the drilling equipment can operate stably and efficiently. When the drilling equipment needs to turn or work in a narrow space, the front beam seat 1 can be flexibly rotated relative to the drive shaft 7 to drive the entire chassis device to adjust the direction, effectively reducing the turning radius of the drilling equipment and improving the maneuverability and operation convenience of the drilling equipment in complex environments.

[0052] As Figure 5 shown, a specific embodiment of the height-adjustable chassis device provided in the embodiment further comprises a second adjustment driving member 8 for driving the front beam seat 1 to rotate relative to the walking device 5.

[0053] Specifically, the second adjustment driving member 8 is used to adjust the state of the drilling rig fixedly connected to the front beam seat 1. When the second adjustment driving member 8 adjusts the angle of the drilling rig to be perpendicular to the ground, subsequent drilling work can be carried out. When the drilling rig needs to be moved to a new position after finishing work, the second adjustment driving member 8 rotates the drilling rig upward by 90° to move above the chassis device, keeping a safe state parallel to the ground. With the adjustment of the position of the drilling rig, the vehicle head will be flipped from the upwardly raised state to the horizontal state to facilitate driving. When encountering complex road conditions during walking, the first adjustment driving member 3 needs to adjust the angle of the rear beam seat 2 to increase the departure angle and the approach angle of the vehicle head, so that the drilling equipment can easily cross obstacles and smoothly pass through complex road conditions.

[0054] As Figure 5 shown, a specific embodiment of the height-adjustable chassis device provided in the embodiment has at least two second adjustment driving members 8 arranged symmetrically.

[0055] Specifically, the at least two symmetrically arranged second adjustment drives 8 greatly optimize the adjustment performance of the front beam seat 1. The symmetric arrangement enables the driving force to act uniformly on both sides of the front beam seat 1, and no matter which side encounters external force interference, the driving elements on both sides can work cooperatively to effectively resist the interference force, avoid the inclination or deviation of the front beam seat 1, and ensure the stability of the front beam seat 1 during rotation. The multiple symmetrically arranged driving elements provide more precise control capability. If one of the driving elements fails, the driving elements at other symmetric positions can still undertake part of the adjustment task, maintain the basic operation capability of the drilling equipment, reduce the risk of equipment downtime caused by failure of a single driving element, and improve the adaptability and working efficiency of the drilling equipment under complex working conditions.

[0056] As shown in Figure 5 a specific embodiment of the height-adjustable chassis device provided by the present embodiment, the second adjustment drive 8 is a linear telescopic drive structure, one end of the second adjustment drive 8 is connected with the front beam seat 1, and the other end of the second adjustment drive 8 is connected with the traveling device 5; the connection position of the second adjustment drive 8 with the front beam seat 1 is higher than the connection position of the second adjustment drive 8 with the traveling device 5, and the connection position of the second adjustment drive 8 with the front beam seat 1 is higher than the driving shaft 7.

[0057] Specifically, the linear telescopic drive structure is simple and direct, the power transmission is efficient, and it can quickly respond to adjustment instructions. Since the connection position of the second adjustment drive 8 with the front beam seat 1 is higher than the connection position with the traveling device 5 and is higher than the driving shaft 7, a good mechanical layout is formed when driving the front beam seat 1 to rotate. It is convenient to accurately control the rotation angle of the front beam seat 1, and then accurately adjust the state of the drilling rig.

[0058] Working principle:

[0059] The front beam seat 1 is stably connected with the traveling device 5 to provide stable support and ensure the stability of the chassis during operation of the drilling equipment. The rear base 2 is rotationally connected with the front beam seat 1, and after the first adjustment drive 3 is started, the rear base 2 is accurately driven to rotate relative to the front beam seat 1, thereby flexibly adjusting the height of the power component 6 fixed on the rear base 2. In complex construction environments, the operator adjusts the height of the power component 6 according to the road conditions by means of the first adjustment drive 3, increases the departure angle and approach angle of the vehicle head, helps the drilling equipment to cross obstacles, and improves the passing ability and obstacle avoidance ability.

[0060] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the present application.
