Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a pile driving chassis and a rotary drilling rig. Background Art

[0002] Piling machinery, including rotary drilling rigs, continuous wall grabs, etc., is an indispensable equipment in infrastructure construction. These machines usually consist of a crawler walking mechanism, a pile driving chassis, and an operating head. In the existing design, the air filter is usually installed near the engine or at the left rear position inside the engine hood. Although this layout simplifies the structure to a certain extent, since the air filter is close to the engine and other heat sources (such as the hydraulic oil radiator and the exhaust system), it often inhales the hot air generated by these devices. This significantly increases the temperature of the air entering the engine, resulting in a decrease in the density of the intake air, a low oxygen intake, and ultimately problems such as a decline in engine performance, fuel consumption, and accelerated wear. Summary of the Utility Model

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a pile driving chassis and a rotary drilling rig, which can solve the problem of the air filter inhaling hot air.

[0004] The technical solution adopted by the utility model to solve its problems is as follows:

[0005] A pile driving chassis, comprising:

[0006] A platform base body, in the middle of which there is an assembly groove arranged along the length direction of the platform base body. The assembly groove divides the platform base body into a first installation area and a second installation area, and an operating head is assembled in the assembly groove;

[0007] An engine, which is arranged in the first installation area or the second installation area along the length direction of the platform base body;

[0008] An air filter, which is arranged at one end of the first installation area along the length direction of the first installation area, and the air inlet of the air filter faces away from the engine side, or the air filter is arranged at one end of the second installation area along the length direction of the second installation area, and the air inlet of the air filter faces away from the engine side.

[0009] By adopting the above scheme, the air inlet of the air filter faces away from the engine side, effectively avoiding inhaling the hot air generated by the engine and other heat sources, thereby reducing the intake air temperature. The low-temperature intake air increases the air density, increases the oxygen amount entering the engine, makes the combustion more complete, improves the working efficiency and output power of the engine, and the low-temperature intake air reduces the wear of the internal parts of the engine, extends the service life of the engine, and reduces the maintenance cost.

[0010] The engine is arranged along the length direction of the platform base body, that is, the engine is longitudinally arranged. In order to horizontally install the engine, the length of the platform base body is extended, which is not conducive to the miniaturization design of the platform base body.

[0011] Furthermore, it further includes a cab. Both the cab and the engine are arranged in the first installation area or the second installation area, and a heat insulation cotton is provided between the cab and the engine.

[0012] By adopting the above scheme, due to the existence of the heat insulation cotton, the heat generated by the engine can be effectively isolated, preventing this heat from directly conducting into the cab, so as to keep the temperature in the cab within a relatively comfortable range. The heat insulation cotton also has a certain sound insulation effect, which helps to reduce the noise level transmitted into the cab during the operation of the engine and improve the comfort of the working environment of the operator.

[0013] Furthermore, the cab is arranged at one end of the first installation area, a first cabinet is arranged at the other end of the first installation area, the engine is arranged in the first cabinet, a cabinet door is arranged on the side of the first cabinet facing away from the assembly groove, and an avoidance opening is arranged at the corresponding position of the first cabinet and the engine oil filling port. A first cover plate is detachably assembled at the avoidance opening.

[0014] By adopting the above scheme, arranging the cab at one end of the first installation area can provide a wider field of vision for the operator, facilitating the observation of the working area and the surrounding environment, and improving the safety and accuracy of the operation. By setting an avoidance opening corresponding to the engine oil filling port on the first cabinet, and a first cover plate is detachably assembled at the avoidance opening, so that the operator can perform oil filling without completely opening the cabinet, improving the convenience of daily maintenance work. A cabinet door is arranged on the side of the first cabinet facing away from the assembly groove, which facilitates the inspection and maintenance work of the engine and its surrounding equipment, reducing the maintenance time and cost.

[0015] Furthermore, an engine oil detection port is arranged on the first cover plate, and a second cover plate is detachably assembled at the engine oil detection port.

[0016] By adopting the above scheme, after removing the second cover plate, the operator can conveniently check the engine oil level and quality at the engine oil detection port without completely opening components such as the cabinet or the first cover plate. This simplifies the daily maintenance process, saving time and labor. When it is necessary to fill the engine oil, the first cover plate can be removed to complete the engine oil filling.

[0017] Further, an engine radiator, a hydraulic pump, and a silencer are also provided inside the first cabinet. The hydraulic pump, the engine, and the engine radiator are arranged in sequence along the length direction of the first installation area. The hydraulic pump is arranged on the side close to the cab. The engine radiator is connected to the engine for cooling the engine. The hydraulic pump is connected to a hydraulic oil tank, and the hydraulic oil tank is arranged in the first installation area.

[0018] By adopting the above scheme, the hydraulic pump, the engine, and the engine radiator are arranged in sequence along the length direction of the first installation area, enabling each component to be arranged compactly together, effectively utilizing the limited space. This layout helps to achieve the miniaturized design of the overall structure. The engine radiator is directly connected to the engine, which can cool the engine more effectively, keep it within the optimal working temperature range, and thus improve the working efficiency and lifespan of the engine. The hydraulic pump is arranged on the side close to the cab, which can reduce the heat transferred from the engine to the cab and further improve the driving environment.

[0019] Further, a silencer is also provided inside the first cabinet. The silencer is arranged above the engine, and the air filter is arranged above the engine radiator.

[0020] By adopting the above scheme, the noise generated during the operation of the engine can be absorbed and reduced more effectively. Since the silencer is directly installed above the engine, it can better capture and process the sound waves emitted from the engine, thus providing a quieter operating environment. The air filter arranged above the engine radiator can avoid inhaling hot air.

[0021] Further, the hydraulic oil tank is arranged between the cab and the hydraulic pump.

[0022] By adopting the above scheme, the hydraulic oil tank located between the cab and the hydraulic pump can play a certain heat insulation role, reducing the direct heat radiation from the engine and other heat sources (such as the hydraulic pump) to the cab, and helping to maintain the comfort of the temperature inside the cab.

[0023] In addition, by setting the hydraulic oil tank at a position relatively far from the engine, the hydraulic oil in the tank can be prevented from being overly affected by heat, thereby better controlling the oil temperature. Stable oil temperature helps to improve the performance and reliability of the hydraulic system.

[0024] Further, a control valve and an electric control box are also included. The control valve is connected to the hydraulic pump through a hydraulic pipeline.

[0025] By adopting the above scheme, the control valve is directly connected to the hydraulic pump through a hydraulic pipeline, which can accurately control the flow direction and pressure of the hydraulic oil, thereby achieving precise control of various actuators (such as the working head of a rotary drilling rig). The electric control box controls the action of the control valve through an electric signal, which can achieve a faster and more accurate response, improving the control accuracy of the entire system.

[0026] Furthermore, both the control valve and the electric control box are arranged in the first installation area or the second installation area, and the engine is arranged opposite to the control valve.

[0027] By adopting the above scheme, the control valve and the electric control box are centrally arranged in the same installation area and are arranged in opposite installation areas to the engine. That is, if the engine is arranged in the first installation area, the control valve and the electric control box are correspondingly arranged in the second installation area, so that the limited space of the first installation area and the second installation area can be utilized more effectively, making the entire chassis structure more compact. This helps to achieve miniaturized design and is especially suitable for medium and small multi-functional pile foundation chassis.

[0028] The present utility model also provides a rotary drilling rig, including the above-mentioned pile foundation chassis.

[0029] By adopting the above scheme, different operation tasks can be completed by selecting a suitable working head, such as a rotary drill and a continuous wall grab. The air inlet of the air filter faces away from the engine side, effectively avoiding the intake of hot air generated by the engine and other heat sources.

[0030] In summary, a pile foundation chassis and a rotary drilling rig provided by the present utility model have the following technical effects:

[0031] 1. The air inlet of the air filter faces away from the engine side, effectively avoiding the intake of hot air generated by the engine and other heat sources, thereby reducing the intake air temperature. The low-temperature intake air increases the air density, increases the amount of oxygen entering the engine, makes the combustion more complete, improves the working efficiency and output power of the engine, and the low-temperature intake air reduces the wear of internal parts of the engine, extends the service life of the engine, and reduces the maintenance cost.

[0032] 2. The engine is arranged along the length direction of the platform base, that is, the engine is longitudinally arranged. Compared with the engine being horizontally arranged on the platform base, the platform base needs to be extended for the horizontal placement of the engine, which is not conducive to the miniaturized design of the platform base;

[0033] 3. Different operation tasks can be completed by selecting a suitable working head, such as a rotary drill and a continuous wall grab. BRIEF DESCRIPTION OF THE DRAWINGS

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0043] Refer toFigures 1 - 4 , the utility model discloses a pile driving chassis, which includes a platform base body 1, an engine 2 and an air filter 3. An assembly groove 11 is provided in the middle of the platform base body 1 along the length direction of the platform base body 1. The assembly groove 11 divides the platform base body 1 into a first installation area 12 and a second installation area 13. A working head 5 is assembled in the assembly groove 11. The engine 2 is arranged in the first installation area 12 or the second installation area 13 along the length direction of the platform base body 1. The air filter 3 is arranged at one end of the first installation area 12 along the length direction of the first installation area 12, and the air inlet 31 of the air filter faces away from the engine 2, or the air filter 3 is arranged at one end of the second installation area 13 along the length direction of the second installation area 13, and the air inlet 31 of the air filter faces away from the engine 2.

[0044] Specifically, an assembly groove 11 is provided in the middle of the platform base body 1 along the length direction of the platform base body 1. The assembly groove 11 divides the areas on both sides of the platform base body 1 where the assembly groove 11 is located into a first installation area 12 and a second installation area 13. A working head 5 is assembled in the assembly groove 11. It is best that the working head 5 is detachably assembled in the assembly groove 11, so that it is convenient to replace a suitable working head 5 for operation. The engine 2 is arranged in the first installation area 12 or the second installation area 13 along the length direction of the platform, that is, the engine 2 is longitudinally arranged. Compared with the engine 2 being horizontally arranged on the platform base body 1, in order to accommodate the horizontal placement of the engine 2, the length of the platform base body 1 is extended, which is not conducive to the miniaturization design of the platform base body 1. The air filter 3 is arranged at one end of the first installation area 12 along the length direction of the first installation area 12, and the air inlet 31 of the air filter 3 faces away from the engine 2, or the air filter 3 is arranged at one end of the second installation area 13 along the length direction of the second installation area 13, and the air inlet 31 of the air filter 3 faces away from the engine 2. Correspondingly, the air inlet 31 of the air filter 3 faces away from the engine 2, so as to effectively avoid inhaling the hot air generated by the engine 2 and other heat sources, thereby reducing the intake air temperature.

[0045] It should be noted that this application mainly introduces the layout methods of various components of the pile driving chassis, and will not further elaborate on the connection methods of some common specific components.

[0046] Refer to Figures 1 - 2 , in some embodiments, the pile driving chassis further includes a cab 4. Both the cab 4 and the engine 2 are arranged in the first installation area 12 or the second installation area 13, and there is a heat insulation cotton between the cab 4 and the engine 2.

[0047] Specifically, due to the presence of the heat insulation cotton, the heat generated by the engine 2 can be effectively isolated, preventing this heat from directly conducting into the cab 4, thereby keeping the temperature inside the cab 4 within a relatively comfortable range. The heat insulation cotton also has a certain sound insulation effect, which helps to reduce the noise level transmitted into the cab 4 when the engine 2 is running, improving the comfort of the working environment for the operator.

[0048] Refer to Figures 1 - 3 , in some embodiments, the cab 4 is provided at one end of the first installation area 12, a first cabinet 6 is provided at the other end of the first installation area 12, the engine 2 is provided inside the first cabinet 6, a cabinet door 61 is provided on the side of the first cabinet 6 facing away from the assembly groove 11, and an avoidance opening is provided at the position of the first cabinet 6 corresponding to the engine oil filling port of the engine 2, and a first cover plate 62 is detachably assembled at the avoidance opening.

[0049] Specifically, arranging the cab 4 at one end of the first installation area 12 can provide a wider field of vision for the operator, facilitating the observation of the working area and the surrounding environment, and improving the safety and accuracy of operation. By providing an avoidance opening on the first cabinet 6 corresponding to the engine oil filling port of the engine 2, and a first cover plate 62 is detachably assembled at this avoidance opening, the operator can perform engine oil filling without completely opening the cabinet, improving the convenience of daily maintenance work. A cabinet door 61 is provided on the side of the first cabinet 6 facing away from the assembly groove 11, facilitating the inspection and maintenance of the engine 2 and its surrounding equipment, and reducing the maintenance time and cost.

[0050] Refer to Figures 1 - 3 , in some embodiments, an engine oil detection port is provided on the first cover plate 62, and a second cover plate 63 is detachably assembled at the engine oil detection port.

[0051] Specifically, by opening the engine oil detection port of the first cover plate 62, the operator can conveniently check the engine oil level and quality of the engine 2 without completely opening components such as the cabinet or the first cover plate 62. This simplifies the daily maintenance process and saves time and labor. When engine oil needs to be filled, the first cover plate 62 can be disassembled to complete the engine oil filling.

[0052] Refer to Figures 1 - 2 , in some embodiments, an engine radiator 64, a hydraulic pump 65 and a silencer 66 are also provided inside the first cabinet 6. The hydraulic pump 65, the engine 2 and the engine radiator 64 are arranged in sequence along the length direction of the first installation area 12. The hydraulic pump 65 is arranged on the side close to the cab 4. The engine radiator 64 is connected to the engine 2 for cooling the engine 2. The hydraulic pump 65 is connected to a hydraulic oil tank 67, and the hydraulic oil tank 67 is provided in the first installation area 12.

[0053] Specifically, a hydraulic pump 65, an engine 2, and an engine radiator 64 are arranged in sequence along the length direction of the first installation area 12, enabling each component to be compactly arranged together, effectively utilizing the limited space. This layout helps to achieve a miniaturized design of the overall structure. The engine radiator 64 is directly connected to the engine 2, which can more effectively cool the engine 2 and keep it within the optimal operating temperature range, thereby improving the operating efficiency and lifespan of the engine 2. The hydraulic pump 65 is arranged on the side close to the cab 4, which can reduce the heat transferred from the engine 2 to the cab 4 and further improve the driving environment.

[0054] Correspondingly, when the hydraulic oil tank 67 is arranged in the first installation area 12, the hydraulic oil tank 67 is adjacent to the cab 4, and heat insulation cotton is arranged between the hydraulic oil tank 67 and the cab 4 to isolate the heat and noise generated by components such as the hydraulic oil tank 67 and the engine 2 behind the cab 4 through the heat insulation cotton.

[0055] Refer to Figures 1 - 2 , in some embodiments, in order to improve the quietness of the pile driving chassis during operation, a muffler 66 is also arranged in the first cabinet 6. The muffler 66 is arranged on the upper side of the engine 2, and the air filter 3 is arranged above the engine radiator 64.

[0056] By adopting the above scheme, the noise generated during the operation of the engine 2 can be more effectively absorbed and reduced. Since the muffler 66 is directly installed above the engine 2, it can better capture and process the sound waves emitted from the engine 2, thereby providing a quieter operating environment. The air filter 3 arranged above the engine radiator 64 can avoid inhaling hot air.

[0057] Refer to Figures 1 - 2 , in some embodiments, in order to further improve the comfort of the cab 4, the hydraulic oil tank 67 is arranged between the cab 4 and the hydraulic pump 65.

[0058] Specifically, the hydraulic oil tank 67 located between the cab 4 and the hydraulic pump 65 can play a certain heat insulation role, reducing the direct heat radiation of the engine 2 and other heat sources (such as the hydraulic pump 65) to the cab 4, which helps to maintain the comfort of the temperature inside the cab 4. In addition, by setting the hydraulic oil tank 67 at a relatively far position from the engine 2, the hydraulic oil in the tank can be prevented from being overly affected by heat, thereby better controlling the oil temperature. Stable oil temperature helps to improve the performance and reliability of the hydraulic system.

[0059] Refer to Figures 1 - 2 , in some embodiments, the pile driving chassis further includes a control valve 7 and an electric control box 8. The control valve 7 is connected to the hydraulic pump 65 through a hydraulic pipeline.

[0060] Specifically, the control valve 7 is directly connected to the hydraulic pump 65 through a hydraulic pipeline, which can precisely control the flow direction and pressure of the hydraulic oil, thereby achieving precise control of various actuators (such as the working head 5 of a rotary drilling rig). The electric control box 8 controls the operation of the control valve 7 through electrical signals, enabling faster and more accurate responses and improving the control accuracy of the entire system. The control valve 7 includes a main valve and an auxiliary valve, and both the main valve and the auxiliary valve are connected to the hydraulic pump 65 through hydraulic pipelines to facilitate more refined work of the working head 5.

[0061] Refer to Figures 1 - 2 , in some embodiments, both the control valve 7 and the electric control box 8 are disposed in the first installation area 12 or the second installation area 13, and the engine 2 is disposed opposite to the control valve 7.

[0062] Specifically, the control valve 7 and the electric control box 8 are centrally arranged in the same installation area and are disposed in opposite installation areas to the engine 2. That is, when the engine 2 is disposed in the first installation area 12, the control valve 7 and the electric control box 8 are correspondingly disposed in the second installation area 13, thereby enabling more effective utilization of the limited space in the first installation area 12 and the second installation area 13 and making the entire chassis structure more compact. This helps to achieve miniaturized design and is particularly suitable for medium and small multi-functional pile driving chassis.

[0063] The following will give an example of an optional connection method between the various components of the above structure:

[0064] The engine 2, air filter 3, hydraulic pump 65, engine radiator 64, and control valve 7 can all be optionally electrically connected to the electric control box 8 for easy control, or indirectly connected to the electric control operation module in the cab 4 for easy control. The air filter 3 is connected to the engine 2 so that the air filtered by the air filter 3 can enter the engine 2. The hydraulic oil tank 67 is connected to the hydraulic pump 65 through a pipeline so that the hydraulic pump 65 can pump the hydraulic oil in the hydraulic oil tank 67 to the control valve 7. The control valve 7 is connected to the working head 5 through a pipeline to control the flow of hydraulic oil to the working head 5 and control the working head 5 to complete the operation. The engine radiator 64 is disposed at the engine 2, and the engine radiator 64 can be selected to be connected by means of fitting or connection according to the specific type. To facilitate the work of the working head 5, a hoisting component can also be correspondingly provided. In addition, a diesel tank, a slewing motor, etc. can be provided on the pile driving chassis, and a footrest can be provided outside the entrance door of the cab 4, and a ladder can be provided in the installation area opposite to the cab 4, which will not be elaborated one by one here.

[0065] Of course, there are other connection methods between the various components, which will not be elaborated here.

[0066] Refer to Figures 1 - 2, in some embodiments, the pile driving chassis is further provided with a hydraulic oil radiator 9, and the hydraulic oil radiator 9 is arranged in the installation area opposite to the air filter 3. In this embodiment, the air filter 3 is arranged in the first installation area 12, and the hydraulic oil radiator 9 is correspondingly arranged in the second installation area 13, further reducing the influence of the heat dissipated by the hydraulic oil radiator 9 on the air filter 3. Correspondingly, the hydraulic oil radiator 9 can be connected to a point in the hydraulic oil circulation pipeline, and the hydraulic oil is cooled by passing through the hydraulic oil radiator 9.

[0067] Refer to Figure 1 , the present invention also provides a rotary drilling rig, including the above-mentioned pile driving chassis.

[0068] By arranging the above-mentioned pile driving chassis on the rotary drilling rig, it can complete different operation tasks by selecting a suitable working head 5, such as a rotary drill and a diaphragm wall grab, etc. The air inlet 31 of the air filter 3 faces away from the engine 2, effectively avoiding the intake of hot air generated by the engine 2 and other heat sources.

[0069] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
