Description

Technical Field

[0001] The utility model relates to a variable load-bearing rubber wheel compacting module applied to snow working conditions, belonging to the technical field of road roller engineering machinery products. Background Art

[0002] Along the coast of the Antarctic continent, in the rocky areas of islands, and even in the Antarctic inland ice sheet, camps need to be set up in an environment with perennial snow. It is impossible to clear the snow and then set up camps on rocks or permafrost like in other areas on Earth. Therefore, the soft snow needs to be compacted before setting up the camp.

[0003] Snow is generally a three-phase material composed of ice (solid), pore water (liquid) and pore air (gas), in which adjacent snow particles are bound together by intergranular bonds. The original undisturbed snow has the characteristics of low density and high compressibility, and will produce a large volume strain after initial compression. Unlike soil materials on land-based surfaces, when the snow layer is compacted using conventional rigid rolling equipment, the intergranular bonds between the snow layers will break or intercrystalline slip, and the compressed snow layer will often fail in a brittle manner under high strain rates. As a result, the compressed snow cannot form a covering layer with a certain strength. Summary of the invention

[0004] Purpose of the invention: In view of the deficiencies in the prior art, the utility model provides a variable load rubber wheel compaction module for use in snow working conditions, which can achieve snow layer compaction operations under different working conditions by adjusting the load and the width of the compaction module.

[0005] Technical solution: A variable load rubber wheel compaction module for use in snow conditions, comprising a compacting rubber wheel group and a first load unit mounted on the compacting rubber wheel group, wherein the first load unit comprises a frame and a counterweight loaded in the frame, and a connecting frame assembly is disposed on the outer side of the frame;

[0006] The frame is an arched frame with a sealed bottom, a counterweight cavity and a filler cavity are arranged in the arched frame, the filler cavity is arranged between the counterweight cavity and the bottom surface of the frame, the counterweight cavity is equipped with a detachable counterweight block, and the filler cavity is filled with a fluid filler;

[0007] The connecting frame assembly includes a first traction assembly arranged in the middle of the front side of the frame and a first connecting frame arranged in the middle of a side of the frame away from the first traction assembly;

[0008] The first traction assembly includes a first lock hook whose one end is hinged to the towing device through a longitudinal pin shaft and a first traction frame fixed to the front side of the frame, a first ear shaft rotating along the axis of the first traction frame is arranged in the middle of the first traction frame, and the first ear shaft is hinged to the other end of the first lock hook through a pin shaft;

[0009] A first connecting portion is disposed in the middle of the first connecting frame, and a detachable pin is disposed longitudinally on the first connecting portion.

[0010] The utility model adopts a rubber wheel group as a snow compactor. The elastic rubber wheels will generate dual loads in the vertical and horizontal directions during the flexible rolling process. The vertical load will make the snow layer more compact, and the horizontal load will cause the snow layer particles to recombine and arrange in the horizontal direction. The two loads compress the gaps between the ice and snow particles from all directions, thereby forming a uniform and dense structure, thereby enhancing the various mechanical properties of the compacted snow layer.

[0011] In view of the compaction operation conditions of the rubber-wheel compaction module on uneven roads in the left and right directions, the utility model releases a rotational freedom around the ear shaft axis on the ear shafts of the front and rear traction frames, so that the front and rear frames can rotate around the ear shafts to adapt to the uneven left and right operation conditions of the rubber-wheel compaction module.

[0012] Preferably, at least one second load-bearing unit is included, and the structure of the second load-bearing unit is the same as that of the first load-bearing unit. A second traction assembly is arranged in the middle of the front side of the second load-bearing unit. The second traction assembly includes a first locking hook whose one end is hinged to the first connecting part through a longitudinal pin shaft, and a second traction frame fixed to the front side of the frame. A second ear shaft that rotates along the axis of the second traction frame is arranged in the middle of the second traction frame, and the second ear shaft is hinged to the other end of the second locking hook through a pin shaft.

[0013] Taking into account that snow layer compaction generally involves multiple compaction construction processes, the compression rubber wheel groups of the front and rear first load unit and the second load unit of the utility model roll over the snow layer, with a considerable amount of overlap during the rolling process, thereby achieving compaction of the snow layer to a certain extent; this can enhance the compaction effect while reducing the number of compaction times, thereby improving work efficiency.

[0014] Preferably, the counterweight cavity comprises a first counterweight cavity that coincides with the projection surface of the arched portion of the frame and a second counterweight cavity located on both sides of the first counterweight cavity, and the depth of the second counterweight cavity is greater than the depth of the first counterweight cavity;

[0015] The counterweight block includes a first counterweight block embedded in a first counterweight cavity and a second counterweight block embedded in a second counterweight cavity. After the first counterweight block and the second counterweight block are assembled, their upper end surfaces are on the same horizontal plane, and the upper ends of the first counterweight block and the second counterweight block are both provided with at least one fixed lifting ring.

[0016] Considering the differences in the physical properties and thickness of snow layers in different regions, different periods of time and different environments, the ground pressure ratio required to compact it without brittle cracking is also different. Substantial ground pressure ratio adjustment can be achieved by increasing / decreasing the number of block weights; the setting of the lifting ring facilitates the lifting of the first and second weight blocks.

[0017] Preferably, a filling port is provided at the upper end of the filling cavity and is connected to the first counterweight cavity, and the filling material is filled into the filling cavity through the filling port. A discharge port is provided at a position corresponding to the lower position of the filling cavity on the side of the frame, and the filling material is discharged from the filling cavity through the discharge port.

[0018] Small and precise ground pressure adjustments can be fine-tuned by adding / reducing the weight of the packing.

[0019] Preferably, at least one additional frame and a matching clamping rubber wheel set can be installed side by side on either the left or right side of the frame, and two adjacent frames are fixedly connected by a connecting plate.

[0020] In view of the compaction requirements of snow-covered roads / campsites of different widths, the utility model adopts a unitized frame design, and independent frame units can be removed or added to change the compaction width; the number of frame assemblies can also be increased or decreased to achieve different degrees of re-compaction effects.

[0021] Preferably, the first connecting frame further comprises a connecting rod fixedly connected to the side of the frame, the first connecting portion is fixedly arranged in the middle of the connecting rod, the first connecting portion comprises an upper limit plate and a lower limit plate which are symmetrical in upper and lower directions, the longitudinal pin shaft penetrates the upper limit plate and the lower limit plate and is detachably connected to the upper limit plate and the lower limit plate;

[0022] It also includes a left limit plate and a right limit plate which are arranged on the left and right sides of the upper limit plate and the lower limit plate and are fixedly connected to the upper limit plate and the lower limit plate.

[0023] In order to avoid interference caused by excessive relative swinging of the front and rear frames, left and right limit plates are designed on the front connecting frame to limit the relative swinging of the front and rear frames. The connecting rod makes the force uniform and can have the same effect as the connecting plate, connecting multiple frames side by side to provide higher connection stability.

[0024] Preferably, a mud scraper inclined downward is fixedly provided on the bottom of the frame near one side of the clamping rubber wheel group, and the width of the mud scraper is greater than or equal to the tire width of a single clamping rubber wheel.

[0025] A scraper symmetrically arranged about the axle cross section is installed near each tread of the rear wheel group. The scraper is fixed to the bottom of the rear frame and is used to remove ice and snow adhering to the rubber wheel when the snow layer is compacted. Scrapers are arranged on both sides of the compacting rubber wheel at the bottom of the arched area of ​​the frame, so that the adhering ice and snow can be scraped off when the vehicle is moving forward or reversed.

[0026] Preferably, a screw elevator is provided on either side of the first traction frame or the second traction frame, and the screw elevator includes a screw for support and a handle for adjusting the screw, and the handle controls the screw to move up and down relative to the frame.

[0027] The spiral lift adopts the ball screw mechanical sliding lifting principle, which can realize the free lifting of large weights and has a self-locking function, with high reliability; because the first locking hook and the second locking hook have a rotational freedom parallel to the wheel axle relative to the first traction frame and the second traction frame, this degree of freedom enables the front and rear frames to adapt to the uneven and rugged road surface, and realize the rubber wheel always in contact with the ground during the compaction process.

[0028] However, when parking on a rough road, the front and rear frames maintain different angles relative to the horizontal direction, which results in the interaction between the second lock hook and the front connecting frame pin shaft adding an oblique component of gravity. Considering the heavy deadweight of the entire compaction module, this oblique component of force has a huge destructive effect on the front connecting frame pin shaft and the upper and lower limit structures nearby. To avoid this situation, the lifting height of the spiral lift can be adjusted to keep the second lock hook parallel to the front frame, avoiding the oblique component of force acting on the front connecting frame, thereby reducing damage to the structure. When parking on rough roads to remove the connection between the tractor and the first lock hook, there may be a certain height difference between the first traction frame and the tractor in the horizontal direction. This height difference causes the first lock hook to have a component force in the horizontal direction acting on the trailer pin of the trailer device, which makes it difficult to release the connection between the first lock hook and the trailer pin. In this case, the lifting height of the spiral lift can be adjusted to make the upper / lower limit heights of the first lock hook and the trailer pin consistent, and then the distance between the trailer device and the first load unit can be adjusted to remove the horizontal pulling force / thrusting force, and the connection can be easily removed. Beneficial Effects

[0029] The utility model adopts a rubber wheel group as a snow compactor. The elastic rubber wheels will generate dual loads in the vertical and horizontal directions during the flexible rolling process. The vertical load will make the snow layer more compact, and the horizontal load will cause the snow layer particles to recombine and arrange in the horizontal direction. The two loads compress the gaps between the ice and snow particles from all directions, thereby forming a uniform and dense structure, thereby enhancing the various mechanical properties of the compacted snow layer.

[0030] In view of the compaction operation conditions of the rubber-wheel compaction module on uneven roads in the left and right directions, the utility model releases a rotational freedom around the ear shaft axis on the ear shafts of the front and rear traction frames, so that the front and rear frames can rotate around the ear shafts to adapt to the uneven left and right operation conditions of the rubber-wheel compaction module.

[0031] Taking into account that snow layer compaction generally involves multiple compaction construction processes, the compression rubber wheel groups of the front and rear first load unit and the second load unit of the utility model roll over the snow layer, with a considerable amount of overlap during the rolling process, thereby achieving compaction of the snow layer to a certain extent; this can enhance the compaction effect while reducing the number of compaction times, thereby improving work efficiency.

[0032] Considering the differences in the physical properties of snow layers and their thickness in different regions, different periods of time and different environments, the ground pressure ratio required to compact them without brittle cracks is also different. Large ground pressure ratio adjustments can be made by increasing / decreasing the number of block weights; small and precise ground pressure ratio adjustments can be finely adjusted by increasing / decreasing the weight of the filler; the setting of the lifting ring facilitates the lifting of the first and second ballast blocks.

[0033] In view of the compaction requirements of snow-covered roads / campsites of different widths, the utility model adopts a unitized frame design, and independent frame units can be removed or added to change the compaction width; the number of frame assemblies can also be increased or decreased to achieve different degrees of re-compaction effects.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] like Figures 1 to 5 As shown, a variable load rubber wheel compaction module applied to snow working conditions includes a compacting rubber wheel group 1 and a first load unit 2 installed on the compacting rubber wheel group 1, wherein the first load unit 2 includes a frame 21 and a counterweight loaded in the frame 21, and a connecting frame assembly 3 is arranged outside the frame 21;

[0048] The frame 21 is an arched frame 21 with a sealed bottom, and a counterweight cavity 211 and a filler cavity 212 are provided in the arched frame 21. The filler cavity 212 is provided between the counterweight cavity 211 and the bottom surface of the frame 21. The counterweight cavity 211 is equipped with a detachable counterweight block, and the filler cavity 212 is filled with a fluid filler.

[0049] The connecting frame assembly 3 includes a first traction assembly 31 disposed in the middle of the front side of the frame 21 and a first connecting frame 32 disposed in the middle of a side of the frame 21 away from the first traction assembly 31;

[0050] like Figure 6 As shown, the first traction assembly 31 includes a first lock hook 311 whose one end is hinged to the towing device through a longitudinal pin shaft and a first traction frame 312 fixed to the front side of the frame 21, and a first ear shaft 313 rotating along the axis of the first traction frame 312 is arranged in the middle of the first traction frame 312, and the first ear shaft 313 is hinged to the other end of the first lock hook 311 through a pin shaft;

[0051] A first connecting portion 321 is disposed in the middle of the first connecting frame 32 , and a detachable pin is longitudinally disposed on the first connecting portion 321 .

[0052] The utility model adopts a rubber wheel group as a snow compactor. The elastic rubber wheels will generate dual loads in the vertical and horizontal directions during the flexible rolling process. The vertical load will make the snow layer more compact, and the horizontal load will cause the snow layer particles to recombine and arrange in the horizontal direction. The two loads compress the gaps between the ice and snow particles from all directions, thereby forming a uniform and dense structure, thereby enhancing the various mechanical properties of the compacted snow layer.

[0053] In view of the compaction working conditions of the rubber-wheel compaction module on uneven roads in the left and right directions, the utility model releases a rotational freedom around the ear axis on the ear shafts of the front and rear traction frames, so that the front and rear frames 21 can rotate around the ear shafts to adapt to the uneven working conditions of the rubber-wheel compaction module on the left and right directions.

[0054] like Figure 7 As shown, it also includes at least one second load unit 4, which has the same structure as the first load unit 2. A second traction assembly 41 is arranged in the middle of the front side of the second load unit 4. The second traction assembly 41 includes a first locking hook 311 whose one end is hinged to the first connecting part 321 through a longitudinal pin shaft, and a second traction frame 412 fixed to the front side of the frame 21. A second ear shaft 413 that rotates along the axis of the second traction frame 412 is arranged in the middle of the second traction frame 412, and the second ear shaft 413 is hinged to the other end of the second locking hook 411 through a pin shaft.

[0055] Taking into account that snow layer compaction generally involves multiple compaction construction processes, the compression rubber wheel group 1 of the front and rear first load unit 2 and the second load unit 4 of the utility model rolls the snow layer, with a considerable amount of overlap during the rolling process, thereby achieving compaction of the snow layer to a certain extent; it can enhance the compaction effect while reducing the number of compaction times, thereby improving work efficiency.

[0056] The counterweight cavity 211 includes a first counterweight cavity 2111 that coincides with the projection surface of the arched portion of the frame 21 and second counterweight cavities 2112 located on both sides of the first counterweight cavity, wherein the depth of the second counterweight cavity 2112 is greater than the depth of the first counterweight cavity 2111;

[0057] The counterweight block includes a first counterweight block 213 embedded in the first counterweight cavity 2111 and a second counterweight block 214 embedded in the second counterweight cavity 2112. After the first counterweight block 213 and the second counterweight block 214 are assembled, their upper end surfaces are on the same horizontal plane, and the upper ends of the first counterweight block 213 and the second counterweight block 214 are both provided with at least one fixedly installed lifting ring 215.

[0058] Considering the differences in the physical properties and thickness of snow layers in different regions, different periods of time, and different environments, the ground pressure ratio required to compact the snow layers without causing brittle cracks is also different. Substantial ground pressure ratio adjustment can be achieved by increasing / decreasing the number of block-shaped counterweights; the provision of the lifting ring 215 facilitates the lifting of the first counterweight block 213 and the second counterweight block 214.

[0059] The filling cavity 212 has a filling port 216 at the upper end thereof which is in communication with the first counterweight cavity 2111 , and the filling material is filled into the filling cavity 212 through the filling port 216 . The side of the frame 21 corresponding to the lower position of the filling cavity 212 has a discharge port 217 , and the filling material is discharged from the filling cavity 212 through the discharge port 217 .

[0060] Small and precise ground pressure adjustments can be fine-tuned by adding / reducing the weight of the packing.

[0061] At least one additional frame 21 and a matching clamping rubber wheel set 1 can be installed side by side on either side of the frame 21 , and two adjacent frames 21 are fixedly connected via a connecting plate 5 .

[0062] In view of the compaction requirements of snow-covered roads / campsites of different widths, the utility model adopts a unitized frame 21 design, and independent frame 21 units can be removed or added to change the compaction width; the number of frame 21 assemblies can also be increased or decreased to achieve different degrees of re-compaction effects.

[0063] In this solution, there are two options for the application of a single frame 21. The first option is a unified load unit. In the frame 21 of a single load unit, the first counterweight cavity 2111 includes four mounting positions for assembling a first counterweight block 213, and the second counterweight cavity 2112 includes two mounting positions for assembling a second counterweight block 214. When a wider compaction width is required, multiple frames 21 are connected side by side through a connecting plate, and corresponding counterweight blocks are respectively assembled.

[0064] The second type is a conventional load unit and an optional load unit. The first counterweight cavity 2111 in the frame 21 of the conventional load unit includes eight mounting positions for assembling the first counterweight block 213, and the second counterweight cavity 2112 includes four mounting positions for assembling the second counterweight block 214; the first counterweight cavity 2111 in the frame 21 of the optional load unit includes four mounting positions for assembling the first counterweight block 213, and the second counterweight cavity 2112 includes two mounting positions for assembling the second counterweight block 214. Under normal circumstances, a single or two conventional load units are used to perform snow compaction work. When a wider compaction width is required, the frames 21 of multiple optional load units are connected side by side through a connecting plate, and corresponding counterweight blocks are respectively assembled.

[0065] When multiple vehicle frames 21 are connected in parallel, the traction frame and the connecting frame are installed at positions close to the middle according to the state of the vehicle frames after being connected in parallel.

[0066] The first connecting frame 32 also includes a connecting rod 322 fixedly connected to the side of the frame 21, the first connecting portion 321 is fixedly arranged in the middle of the connecting rod 322, the first connecting portion 321 includes an upper limit plate 323 and a lower limit plate 324 symmetrically arranged in a vertical direction, and the longitudinal pin shaft penetrates the upper limit plate 323 and the lower limit plate 324 and is detachably connected to the upper limit plate 323 and the lower limit plate 324;

[0067] The left limit plate 325 and the right limit plate 326 are arranged on the left and right sides of the upper limit plate 323 and the lower limit plate 324 and are fixedly connected to the upper limit plate 323 and the lower limit plate 324 .

[0068] In order to avoid interference caused by excessive relative swinging of the front and rear frames 21, a left limit plate 325 and a right limit plate 326 are designed on the front connecting frame to limit the relative swinging of the front and rear frames 21. The connecting rod makes the force uniform and can have the same effect as the connecting plate, connecting multiple frames 21 side by side to provide higher connection stability.

[0069] A mud scraper 6 tilted downward is fixedly provided at the bottom of the frame 21 near one side of the clamping rubber wheel group 1 , and the width of the mud scraper 6 is greater than or equal to the tire width of a single clamping rubber wheel.

[0070] A scraper 6 symmetrical about the axle cross-section is installed near each tread of the rear wheel group. The scraper 6 is fixed to the bottom of the rear frame 21 and is used to remove ice and snow adhering to the rubber wheel when the snow layer is compacted. The scrapers 6 are respectively arranged on both sides of the compacting rubber wheel at the bottom of the arched area of ​​the frame 21, so that the adhered ice and snow can be scraped off when the vehicle is moving forward or reversed.

[0071] A screw elevator 7 is provided on either side of the first traction frame 312 or the second traction frame. The screw elevator 7 includes a supporting screw 71 and a handle 72 for adjusting the screw 71. The handle 72 controls the screw 71 to move up and down relative to the frame 21.

[0072] The spiral lift 7 adopts the mechanical sliding lifting principle of the ball screw 71, can realize the free lifting of large weights and has a self-locking function, and has high reliability; since the first locking hook 311 and the second locking hook 411 have a rotational freedom parallel to the wheel axle relative to the first traction frame 312 and the second traction frame, this degree of freedom enables the front and rear frames 21 to adapt to the uneven and rugged road surface front and rear, and realize the rubber wheel always in contact with the ground during the compaction process.

[0073] like Figure 8 and 9 As shown, when parking on a rough road, the front and rear frames 21 maintain different angles relative to the horizontal direction, which causes the interaction between the second lock hook 411 and the front connecting frame pin to increase an oblique component of gravity. Considering the large deadweight of the entire compaction module, the oblique component has a huge destructive effect on the front connecting frame pin and the upper and lower limit structures nearby. To avoid this situation, the lifting height of the spiral lift 7 can be adjusted so that the second lock hook 411 remains parallel to the front frame 21, avoiding the oblique component from acting on the front connecting frame to reduce damage to the structure. When parking on rough roads and removing the connection between the tractor and the first lock hook 311, there may be a certain height difference in the horizontal direction between the first traction frame 312 and the tractor. This height difference causes the first lock hook 311 to have a component force in the horizontal direction acting on the trailer pin of the trailer device, which makes it difficult to release the connection between the first lock hook 311 and the trailer pin. In this case, the lifting height of the spiral lift 7 can be adjusted to make the upper / lower limit heights of the first lock hook 311 and the trailer pin consistent, and then the distance between the trailer device and the first load unit 2 is adjusted to remove the horizontal pulling force / thrusting force, and the connection can be easily removed.

[0074] One implementation method of this scheme is as follows:

[0075] The right side of the first locking hook is connected to the trailer hook of the trailer device to provide power for the entire module; the left side of the first locking hook is connected to the first traction frame in an articulated manner, wherein there is a rotational freedom in the same direction as the wheel axle between the first locking hook and the first traction frame; the first traction frame is connected to the frame by bolt fastening, the bottom of the frame is supported by a compression rubber wheel set, and a scraper blade symmetrical to the wheel axle cross section is installed near each tread of the wheel set, and the scraper blade is fixed to the bottom of the frame;

The frame of the conventional load-bearing unit includes eight small counterweight cavities, four large counterweight cavities, and two stuffing cavities, and the frame unit of the optional load-bearing unit includes four small counterweight cavities, two large counterweight cavities, and two stuffing cavities. The small counterweight cavity can accommodate a first counterweight block, and the large counterweight cavity can accommodate two second counterweight blocks; the frame of the conventional load-bearing unit and the frame of the optional load-bearing unit are fixed to each other by connecting plates; the left side of the frame is connected to the first connecting frame by bolt fastening; the left side of the front connecting frame is connected to the right side of the second locking hook by hinged manner, wherein there is a rotational freedom perpendicular to the ground between the second locking hook and the front connecting frame; the second The left side of the locking hook is connected to the second traction frame in an articulated manner, wherein there is a rotational freedom in the same direction as the wheel axle between the second locking hook and the second traction frame; the second traction frame is connected to the frame of the second load-carrying unit by bolt-fastening; the bottom of the frame of the second load-carrying unit is supported by the rear wheel set, and a scraper symmetrical about the axial cross-section of the wheel axle is installed near each tread of the rear wheel set, and the scraper is fixed to the bottom of the rear frame; the rear frame is composed of the frames of two conventional load-carrying units, and the frames of the two conventional load-carrying units are fixed to each other by a connecting plate; a second connecting frame is arranged on the left side of the frame of the second load-carrying unit and is connected by bolt-fastening, and the filling cavity of the frame described in the utility model can be filled with fluid fillers such as iron sand or steel balls.
