Description

Technical Field

[0001] This invention relates to a walking device, and more particularly to an electrically driven buffer-type beam transporter walking device, belonging to the field of beam transporter technology. Background Technology

[0002] With the development of electrification in construction machinery, electric drive walking devices have gradually replaced traditional hydraulic and internal combustion engine drive methods due to their advantages such as high speed regulation accuracy, fast start and stop response, and stable operation. They have become the mainstream technical solution for beam-moving machine walking devices. To ensure that the drive motor works reliably under heavy load and low speed conditions, it is necessary to effectively dissipate heat from it.

[0003] Existing motor cooling methods are mainly divided into two types: built-in sealed cooling and external cooling. Although built-in sealed cooling can isolate the motor from the influence of harsh external environments, it requires an independent cooling cycle system, resulting in a complex overall structure and high energy consumption. External cooling can directly utilize external air for cooling, and its structure is relatively simple. However, due to the influence of the working environment, a large amount of dust easily adheres to the surface of the motor housing and cooling fins, which seriously reduces the cooling efficiency. If manual cleaning is used, it is not only inconvenient and inefficient, but also cannot be cleaned in a timely manner. If a dedicated automatic cleaning mechanism is added, it will further increase the system's energy consumption and structural complexity.

[0004] To address these issues, an electrically driven, buffered traveling device for the beam-moving machine was designed. Summary of the Invention

[0005] The main objective of this invention is to provide an electrically driven, buffered, traveling device for a beam-lifting machine. By externally mounting the drive motor on the top of the lower support and using external heat dissipation for cooling, it is equipped with a pulse-blowing dust removal system. This retains the advantages of a simple external heat dissipation structure, high heat exchange efficiency, and the elimination of the need for a high-energy-consuming independent refrigeration system. Furthermore, through the linkage design between the air supply mechanism and the traveling buffer action of the beam-lifting machine, the buffer displacement provides a non-powered air source for pulse-blowing. Combined with a lifting mechanism that drives the pulse air pipe to reciprocate, pulse-type dust removal is achieved without dead angles on the motor surface. The entire process requires no additional power consumption or manual cleaning, solving the problem of reduced heat dissipation efficiency caused by dust accumulation on the external motor. This ensures the stability of motor heat dissipation while reducing equipment energy consumption and maintenance costs, and improving operational reliability. By installing disc springs between the upper and lower supports, and using them in conjunction with the hydraulic buffer inside the mounting base, double buffering is provided during beam-lifting machine movement. This effectively absorbs the vertical impact from uneven road surfaces during the beam-lifting machine's movement, ensuring stability during movement.

[0020] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto. Example 1:

[0021] like Figures 1-9As shown, this embodiment provides an electric drive buffer type beam moving machine traveling device, including a balance beam 1, mounting seats 2 fixed on both sides of the balance beam 1, and traveling wheels 3; the bottom of each mounting seat 2 is provided with an upper support 4, and the bottom of each upper support 4 is provided with a lower support 5. A disc spring 9 is provided between the upper support 4 and the lower support 5. During heavy-load traveling, when encountering uneven road surface or vertical impact caused by starting, stopping, accelerating and decelerating, a vertical relative displacement will occur between the upper support 4 and the lower support 5. The disc spring 9 set between the two undergoes elastic deformation to absorb the impact energy, realize vertical buffering and vibration reduction, and avoid single wheel overload.

[0022] A steering mechanism 10 is provided between the equalizing beam 1 and the mounting base 2 to drive the traveling wheels 3 to complete steering adjustment. When steering is required, the steering mechanism 10 outputs power to drive the upper support 4, lower support 5 and traveling wheels 3 under the mounting base 2 to complete the angle deflection, so as to realize the steering and oblique movement of the beam moving machine, which can adapt to the operation requirements of complex sites.

[0023] A transmission gearbox 6 is installed on the top of the lower support 5. The output end of the transmission gearbox 6 is connected to the walking wheel 3 through a wheel axle. The power input end of the transmission gearbox 6 is connected to the drive motor 7. When the machine is in motion, the drive motor 7 outputs power and transmits torque to the transmission gearbox 6. After the transmission gearbox 6 reduces speed and increases torque, it drives the walking wheel 3 to rotate through the wheel axle, thus realizing the walking, starting and stopping, and micro-motion positioning of the entire beam moving machine.

[0024] A pulse air pipe 11 is coaxially sleeved on the outer side of the drive motor 7, and pulse nozzles 12 facing the housing of the drive motor 7 are evenly opened on the inner side wall of the pulse air pipe 11. The bottom of the upper support 4 is provided with a lifting mechanism 13, which is used to drive the pulse air tube 11 to move up and down along the axis of the drive motor 7. The upper support 4 is equipped with an air supply mechanism 14. The air supply mechanism 14 uses the vertical relative displacement of the support during buffering to drive and generate compressed gas, providing an air source for the pulse air tube 11 and the lifting mechanism 13.

[0025] The vertical relative displacement of the upper support 4 and the lower support 5 synchronously drives the air supply mechanism 14 to operate. The air supply mechanism 14 uses this relative displacement to generate compressed gas. One path of the compressed gas is delivered to the pulse air pipe 11, which is sprayed out towards the housing and heat sink of the drive motor 7 through the pulse nozzle 12, forming a pulsed blowing airflow to peel off the dust and mud deposits attached to the surface of the drive motor 7. The other path of compressed gas is delivered to the lifting mechanism 13 to provide power for the lifting mechanism 13, which drives the pulse air pipe 11 to move up and down along the axial direction of the drive motor 7, so as to achieve a thorough cleaning of the outer surface of the drive motor 7 without dead angles. No additional power is required throughout the process. The dust removal operation can be completed by simply using the buffer action that will inevitably occur during the movement of the equipment, ensuring the heat dissipation stability of the drive motor 7 under heavy load and low speed conditions. Example 2:

[0026] The solution in Example 1 will be further described below with reference to its specific working method. In this embodiment, the disc spring 9 is vertically disposed between the ends of the upper bracket 4 and the lower bracket 5; both ends of the top of the lower bracket 5 are vertically fixed with a sliding rod 8, which passes through the interior of the disc spring 9 axially, and the upper part of the sliding rod 8 is vertically slidably connected to the upper bracket 4. The sliding rod 8 provides guidance and limitation for the deformation of the disc spring 9, and at the same time constrains the relative movement direction of the upper bracket 4 and the lower bracket 5, ensuring that the two can only slide vertically relative to each other along the axial direction of the sliding rod 8, avoiding horizontal misalignment and ensuring the matching accuracy of the transmission structure.

[0027] When a vertical impact occurs, the upper support 4 slides downward along the slide rod 8, compressing the disc spring 9 and causing elastic deformation, converting the impact kinetic energy into the elastic potential energy of the disc spring 9, thus absorbing and dissipating the impact energy. When the impact disappears, the elastic potential energy of the disc spring 9 is released, pushing the upper support 4 to reset. During this process, the slide rod 8 always provides precise guidance for the relative movement of the upper and lower supports, while avoiding radial instability of the disc spring 9 during compression and reset, ensuring the long-term reliable operation of the buffer structure.

[0028] In this embodiment, the steering mechanism 10 includes a hydraulic cylinder 1001, a push plate 1002, a connecting ring 1003, a slide groove 1004, and a steering guide column 1005. The hydraulic cylinder 1001 is hinged to the bottom of the equalizer beam 1. The slide groove 1004 is opened at the inner bottom of the mounting base 2. The steering guide column 1005 is vertically rotatably installed inside the slide groove 1004. The connecting ring 1003 is sleeved on the outer side of the steering guide column 1005. The push plate 1002 is fixed to the outer side wall of the connecting ring 1003. The piston rod output end of the hydraulic cylinder 1001 is hinged to the push plate 1002.

[0029] During steering, the piston rod of the hydraulic cylinder 1001 extends and retracts, causing the push plate 1002 to swing in an arc. The push plate 1002 drives the steering guide column 1005 to rotate in the slide groove 1004 through the connecting ring 1003. The steering guide column 1005 slides with the mounting base 2, thereby causing the entire set of traveling wheels under the mounting base 2 to deflect around the axis of the steering guide column 1005, thus realizing the adjustment of the steering angle of the traveling wheels 3.

[0030] In this embodiment, the steering guide column 1005 can slide vertically along the axial direction of the slide groove 1004. A plane bearing 1006 is installed at the top of the steering guide column 1005. The plane bearing 1006 can isolate the rotation of the steering guide column 1005 from the fixed structure of the hydraulic buffer 1008, so as to prevent the hydraulic buffer 1008 from rotating synchronously when the steering guide column 1005 rotates.

[0031] A hydraulic buffer 1008 is provided between the inner top of the slide groove 1004 and the plane bearing 1006. When the vertical impact load is transmitted to the mounting base 2, the steering guide column 1005 can slide vertically along the axial direction of the slide groove 1004 to transmit the impact load to the plane bearing 1006, and then to the hydraulic buffer 1008 through the plane bearing 1006. The hydraulic buffer 1008 converts the impact kinetic energy into heat energy and dissipates it through internal damping and throttling, realizing secondary buffering and energy absorption. Together with the disc spring 9, it forms a double buffer protection, further reducing the damage of the impact to the steel structure of the whole machine.

[0032] The outer side wall of the steering guide column 1005 is uniformly provided with spline grooves 1007 along the circumference. The inner side wall of the connecting ring 1003 is provided with a transmission protrusion that matches the spline groove 1007. The connecting ring 1003 is circumferentially limited and axially slidably connected to the steering guide column 1005 through the spline groove 1007.

[0033] The mating structure between the spline groove 1007 and the inner transmission protrusion of the connecting ring 1003 can ensure that the steering torque output by the hydraulic cylinder 1001 can be stably transmitted to the steering guide column 1005 through circumferential limiting, thereby achieving precise control of the steering angle. It can also achieve independent operation of the steering function and the buffering function without interfering with each other through axial sliding, thus ensuring the reliability of the operation of the two mechanisms.

[0034] In this embodiment, the air supply mechanism 14 includes a cylinder 1401, a piston 1402, an intake pipe 1404, and an exhaust pipe 1403. The cylinder 1401 is fixed on both sides of the top of the upper bracket 4. The piston 1402 is slidably disposed inside the cylinder 1401. The top end of the slide rod 8 extends into the interior of the cylinder 1401 and is fixedly connected to the bottom of the piston 1402. When the device is subjected to a vertical impact, the upper bracket 4 and the lower bracket 5 are relatively displaced. The lower bracket 5 drives the slide rod 8 to move, and the slide rod 8 pushes the piston 1402 to slide inside the cylinder 1401.

[0035] A one-way intake valve is provided on one side of the top of the cylinder 1401, and a one-way exhaust valve is installed on the other side of the top of the cylinder 1401. An exhaust pipe 1403 is installed at the outlet end of the one-way exhaust valve. The outlet end of the exhaust pipe 1403 is connected to the pulse air pipe 11 and the power input end of the lifting mechanism 13, respectively.

[0036] Piston 1402 slides upward within cylinder 1401, compressing the air at the top of cylinder 1401. At this time, the one-way intake valve is closed and the one-way exhaust valve is open. The high-pressure gas compressed within cylinder 1401 enters exhaust pipe 1403 through the one-way exhaust valve, and is then delivered to pulse air pipe 11 and lifting mechanism 13 through exhaust pipe 1403, providing air source for purging operation and lifting drive. When the impact disappears and the upper support 4 and lower support 5 move away from each other and reset, slide rod 8 drives piston 1402 to slide downward within cylinder 1401, creating negative pressure at the top of cylinder 1401. At this time, the one-way exhaust valve is closed and the one-way intake valve is open, allowing outside air to enter cylinder 1401 through the one-way intake valve, completing the intake process and preparing for the next compression air supply.

[0037] In this embodiment, the lifting mechanism 13 includes a reciprocating lead screw 1301, a slider 1302, a pneumatic motor 1305, and a transmission assembly. The reciprocating lead screw 1301 is symmetrically and vertically rotated on the lower bracket 5, and the two sets of reciprocating lead screws 1301 are respectively located on both sides of the drive motor 7. The slider 1302 is threadedly driven to the reciprocating lead screw 1301, and the side of the slider 1302 is fixedly connected to the outer wall of the pulse air tube 11. The two sets of reciprocating lead screws 1301 arranged symmetrically can synchronously drive the pulse air tube 11 to rise and fall through the sliders 1302 on both sides, ensuring the stability of the pulse air tube 11 during the rising and falling process.

[0038] The pneumatic motor 1305 is fixedly installed at the bottom of the upper bracket 4. The air inlet of the pneumatic motor 1305 is connected to the air supply output end of the air supply mechanism 14. The power output end of the pneumatic motor 1305 is connected to the end of the reciprocating screw 1301 through the transmission assembly.

[0039] The compressed gas output from the air supply mechanism 14 is delivered to the pneumatic motor 1305, which drives the output shaft of the pneumatic motor 1305 to rotate. The pneumatic motor 1305 transmits power to the reciprocating screw 1301 through the transmission assembly, causing the reciprocating screw 1301 to rotate around its own axis. When the reciprocating screw 1301 rotates, it drives the slider 1302 to move back and forth along the axial direction of the reciprocating screw 1301 through the threaded transmission. In turn, the slider 1302 drives the pulse air pipe 11 to move back and forth along the axial direction of the drive motor 7, so that the pulse nozzle 12 on the pulse air pipe 11 can cover the entire height range of the drive motor 7 housing, realizing continuous cleaning of the outer surface of the drive motor 7 from top to bottom without dead angles, avoiding cleaning blind spots, and ensuring the thoroughness of dust cleaning.

[0040] In this embodiment, the transmission assembly includes two sets of pulleys 1303 and a transmission belt 1304; the pulleys 1303 are respectively fixed to the top ends of two sets of reciprocating lead screws 1301, and the two sets of pulleys 1303 are connected by the transmission belt 1304. The output shaft of the pneumatic motor 1305 is connected to one set of reciprocating lead screws 1301.

[0041] When the pneumatic motor 1305 drives one set of reciprocating lead screws 1301 to rotate, the reciprocating lead screw 1301 drives the pulley 1303 at its top to rotate synchronously. The power is transmitted to the pulley 1303 at the top of the other set of reciprocating lead screws 1301 through the transmission belt 1304, thereby driving the two sets of reciprocating lead screws 1301 to rotate synchronously, ensuring that the sliders 1302 on both sides can rise and fall synchronously.

[0042] In this embodiment, an intake pipe 1404 is connected to the intake port of the one-way intake valve at the top of the cylinder 1401, and a filter element 1405 is installed inside the intake pipe 1404.

[0043] Filter element 1405 can filter the outside air drawn into cylinder 1401 and intercept solid impurities such as dust and sand in the air.

[0044] In this embodiment, a protective shell is provided on the inner top of the upper bracket 4, and the transmission component is located inside the protective shell.

[0045] To isolate the construction site from dust, mud, and splashing gravel, preventing impurities from entering the transmission pair and causing wear on pulley 1303.

[0046] In this embodiment, a U-shaped protective plate is vertically fixed on the outer side of the reciprocating lead screw 1301, the slider 1302 slides with the inner side wall of the U-shaped protective plate, and dustproof bristles are provided at the outer opening of the U-shaped protective plate.

[0047] To prevent dust and mud from adhering directly to the thread groove of the reciprocating lead screw 1301, and to prevent wear and jamming of the threaded pair due to impurities entering.

[0048] The solutions in Embodiment 1 and Embodiment 2 will be further described below with reference to their specific working methods. In the walking drive stage, the drive motor 7, together with the transmission gearbox 6, provides low-speed, high-torque power output to the walking wheels 3. Together with the frequency conversion control system, it enables the smooth start and stop of the whole machine, meeting the walking requirements in the transportation of precast beams.

[0049] In the buffering and vibration reduction stage, when the equipment is subjected to vertical impact during movement, the disc spring 9 first completes the primary buffering, quickly absorbing most of the impact energy and limiting the peak value of the impact load; the remaining impact load is transmitted to the hydraulic buffer 1008 through the steering guide column 1005, and the hydraulic buffer 1008 completes the secondary buffering and energy absorption, preventing the whole machine from bumping and vibrating.

[0050] In the dust removal and heat dissipation process, the vertical relative displacement between the upper support 4 and the lower support 5 generated during the buffering and vibration reduction process directly serves as the power source for the air supply mechanism 14, driving the air supply mechanism 14 to continuously generate compressed gas without consuming additional electricity. The compressed gas is divided into two paths. One path directly enters the pulse air pipe 11, forming a high-speed pulse airflow through the pulse nozzle 12, continuously blowing the housing and heat sink of the drive motor 7, peeling off the attached dust deposits, ensuring that the heat dissipation surface of the drive motor 7 remains clean, and ensuring that the temperature rise of the drive motor 7 under heavy load and low speed conditions remains within a reasonable range. The other path of compressed gas drives the lifting mechanism 13 to operate, causing the pulse air pipe 11 to reciprocate up and down along the axis of the drive motor 7, achieving full-range, dead-angle-free blowing. The entire dust removal and heat dissipation process is synchronized with the equipment movement and buffering process, realizing real-time online cleaning without any manual shutdown operation.

[0051] During the steering operation, the hydraulic cylinder 1001 of the steering mechanism 10 can precisely control the steering angle of the traveling wheel 3. At the same time, through the cooperation structure of the spline groove 1007, the steering function and the buffering function do not interfere with each other, ensuring that the equipment can still maintain a good buffering and vibration reduction effect during the steering process.

[0052] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
