A soft foundation reinforcing device for highway construction

Abstract

The application belongs to the technical field of municipal construction, in particular to a soft foundation reinforcing device for highway construction, which comprises a pressurizing component, a centrifugal component is arranged on the top of the pressurizing component, and buffer components are arranged on the two sides of the centrifugal component, which are used to limit the movement of the internal structure of the centrifugal component and prevent the centrifugal component from separating from the pressurizing component. Since different road surfaces have different widths, in order to make the road roller applicable to different road surfaces, the roller width of the road roller is usually designed to be small. When the road roller is used to roll and reinforce the road surface, the road roller needs to move back and forth until the entire road surface is rolled, which leads to a relatively low working efficiency of the road roller. However, the device can be adjusted according to road surfaces with different widths, so that the device can reinforce and flatten the entire road surface through one-way movement, thereby effectively improving the efficiency and avoiding problems such as missed rolling and overpressure caused by reciprocating rolling of the road surface.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of municipal construction, in particular to a soft foundation reinforcement equipment for highway construction. BACKGROUND

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance and management of highway structures, and the highway engineering structures include: roadbed, pavement, bridge, culvert, tunnel, drainage system, safety protection facilities, greenery and traffic monitoring facilities, as well as the houses, workshops and other service facilities used for construction, maintenance and monitoring. If there is no stable roadbed during highway construction, the constructed highway will be damaged soon, so it is necessary to use foundation reinforcement equipment to reinforce the relatively soft roadbed before paving the pavement.

[0003] Due to different pavement widths, in order to make the road roller applicable to different pavements, the roller width of the road roller is usually designed to be small. When the road roller is used to roll and reinforce the pavement, the road roller needs to move back and forth until the entire pavement is rolled, which leads to a relatively low working efficiency of the road roller and the road roller cannot adapt to various pavements, so improvement is needed.

When the pressure plate slides along the root of the inner wall of the counterweight shell, the air inside the counterweight shell can be squeezed out through the air vents. The pressurizing components are divided into two groups, left and right. There are four side sliding plates, with each pressurizing component having side sliding plates on both sides to guide the sliding of its respective impact block.

[0010] The beneficial effects of the present application are as follows:

[0011] 1. Since different road surfaces have different widths, in order to make the road roller applicable to different road surfaces, the width of the roller of the road roller is usually designed to be small, and when the road roller is used to roll and reinforce the road surface, the road roller needs to be reciprocatingly moved until the entire road surface is rolled and reinforced, which leads to a relatively low working efficiency of the road roller, and the device can be adjusted according to different widths of the road surface, so that the device can reinforce and flatten the entire road surface through one-way movement, thereby effectively improving the efficiency and avoiding problems such as missing pressure and overpressure caused by reciprocatingly pressing the road surface.

[0012] 2. When the impact block of the device presses the road surface, the impact force on the road surface can be adjusted according to the rotation speed of the torque rotating machine, so as to avoid the road surface being damaged due to the impact block pressing the road surface with too large an impact force, and also avoid the road surface being not ideally reinforced due to the impact block pressing the road surface with too small an impact force.

[0013] 3. Because the centrifugal force is indirectly applied to the impact block through the pressurizing top plate, the pressurizing top plate can apply a more uniform extrusion force to the impact block after the impact block is separated on both sides, thereby avoiding the problem that the force is easily concentrated in the middle of the solid frame after the impact block moves, resulting in uneven reinforcement on both sides of the road surface.

[0014] 4. Because the torque rotating machine has a large working load, a cutting groove is formed at the bottom of the center part of the centrifugal cylinder for better heat dissipation of the torque rotating machine, and the one-way centrifugal block on both sides can drive the gas flow in the centrifugal cylinder during rotation, thereby enhancing the heat dissipation effect of the torque rotating machine and avoiding the problem of overloading of the torque rotating machine under continuous work in a high-strength working state.

[0015] 5. The buffer component is mainly used to limit the movement of the pressurizing top plate, prevent the pressurizing top plate from separating from the inside of the solid frame, and the spring insertion rod and the built-in spring can absorb the upward impact force of the pressurizing top plate, then convert the impact force into downward extrusion force, thereby enhancing the downward impact effect of the impact block.

The bottom of the impact block 16 extends to the outside of the solid frame 11. The pressurized top plate 21 can slide with the inner wall of the solid frame 11 through the cutting groove above the top of the inner wall of the solid frame 11. Under the limiting action of the buffer part 3, the pressurized top plate 21 will not completely slide out of the inside of the solid frame 11 upward, causing the pressurized top plate 21 to separate from the solid frame 11. The lower surface of the pressurized top is uniformly provided with sliding balls 22. The two sides of the upper surface of the pressurized top are fixedly connected with connecting bent rods 24. The top end of the connecting bent rod 24 is fixedly connected with a centrifugal cylinder 23. The inner wall of the centrifugal cylinder 23 is provided with a torque rotating machine 25.

The top of the output shaft of the torque rotating machine 25 is fixedly connected with an extension rotating rod 26. The surface of the extension rotating rod 26 is fixedly connected with a one-way centrifugal block 4.

[0028] The unidirectional centrifugal block 4 comprises a counterweight shell 41 which is cast from heavy steel material, a pressurizing insert plate 43 is slidingly connected to the bottom of the inner wall of the counterweight shell 41, the outer shape of the pressurizing insert plate 43 is matched with the root of the inner wall of the counterweight shell 41, the upper surface of the pressurizing insert plate 43 is uniformly provided with force receiving push rods 42, the left and right sides of the inner wall of the counterweight shell 41 are uniformly provided with alternating air outlets 44, and when the pressurizing insert plate 43 slides along the root of the inner wall of the counterweight shell 41, the air in the counterweight shell 41 can be extruded out through the alternating air outlets 44. The number of the pressurizing components 1 is two, the pressurizing components 1 are divided into left and right groups, the number of the side sliding plates 12 is four, each pressurizing component 1 is provided with a side sliding plate 12 on the left and right sides, which is used for guiding the sliding of the respective impact blocks 16, the surface of the side sliding plate 12 is slidingly connected with one side of the inner wall of the solid frame 11, the inner wall of the side sliding plate 12 is uniformly provided with air inlets 13 near the side close to the air pump 14, the air inlets 13 are provided for providing air inlets for the air pump 14 in the side sliding plate 12, the surface of the sliding cylinder 17 is slidingly connected with the inner wall of the side sliding plate 12, and the bottom end of the return spring 18 is fixedly connected with the bottom of the inner wall of the side sliding plate 12. The number of the parallel clamps 27 is two, the end of the extension rotating rod 26 away from the torque rotating machine 25 is slidingly connected with the inner wall of the centrifugal cylinder 23, the shaft center of the bottom of the inner wall of the centrifugal cylinder 23 is provided with a cutting groove, the front and rear sides of the surface of the solid frame 11 are symmetrically provided with the power components 5, and the power components 5 are used for driving the device to move on the ground and are the main power source of the device.

[0029] When the device is used, the device is placed horizontally on the road surface to be reinforced, at this time, the power components 5 on the front and rear sides support the pressurizing components 1 as a whole upwards, the solid frame 11 is slightly off the ground, and then the pressurizing components 1 are adjusted according to the width of the ground.

[0030] The air pump 14 in the side sliding plate 12 is controlled to inflate the inner cavity of the connecting pipe sleeve 15 through the air inlets 13, at this time, the connecting pipe sleeve 15 is inflated and expanded, and then gradually elongated, the side sliding plates 12 on the two sides are pushed outwards to the outside of the solid frame 11, at this time, under the pushing action of the sliding cylinder 17, the impact blocks 16 are also pushed outwards, until the impact blocks 16 on the two sides reach the edge position of the road surface to be pressed, the work of the air pump 14 is stopped, and the maximum inflation threshold of the air pump 14 is set to determine the maximum elongation length of the connecting pipe sleeve 15.

[0031] When the device is used, the power components 5 on both sides control the straight movement of the pressing component 1 along the road surface, at this time, the centrifugal component 2 above starts to work, the internal torque rotating machine 25 starts to rotate at high speed, and the rotating one-way centrifugal block 4 is rotated through the extension rotating rod 26 on both sides. Since the extension rotating rod 26 is provided with the one-way centrifugal block 4 on only one side, when the one-way centrifugal block 4 rotates to the upper side, the one-way centrifugal block 4 will slide upward due to the centrifugal force dragging the extension rotating rod 26, at this time, the torque rotating machine 25 and the vertical sliding block 28 will slide upward along the inner wall of the parallel clamping plate 27, and the centrifugal cylinder 23 will also move upward due to the upward centrifugal force dragging the pressing top plate 21, but the buffer component 3 on both sides will limit the pressing top plate 21 to prevent the pressing top plate 21 from separating from the solid frame body 11; when the one-way centrifugal block 4 rotates to the lower side, under the action of the centrifugal force and its own gravity, the centrifugal cylinder 23 as a whole will press the pressing top plate 21 downward, thereby extruding the impact block 16 below downward, at this time, the impact block 16 slides downward along the vertical sliding groove of the side sliding plate 12 through the sliding cylinder 17 on both sides, and after the impact block 16 slides out of the solid frame body 11, it impacts the ground below to achieve the effect of pressing the ground, and then the impact block 16 is retracted into the solid frame body 11 under the upward centrifugal force provided by the centrifugal component 2, preparing for the next impact work.

[0032] With the continuous impact work of the impact block 16, the connecting pipe sleeve 15 is continuously elongated, so that the actual impact range of the impact block 16 is expanded to the entire road surface, and then the entire road surface is impact reinforced through the movement effect of the power component 5.

[0033] When the one-way centrifugal block 4 rotates to the upper position, the vertical sliding block 28 vertically slides upward under the guidance of the parallel clamping plate 27, at this time, the outer surface of the counterweight shell 41 is extruded with the top of the inner wall of the centrifugal cylinder 23, so that the protruding stress push rod 42 is also extruded with the top of the inner wall of the centrifugal cylinder 23, then the stress push rod 42 extrudes the pressing insert plate 43 along the inner wall of the counterweight shell 41, so that the gas in the counterweight shell 41 is discharged through the alternating gas port 44 on both sides, driving the airflow in the centrifugal cylinder 23 to flow, so that the torque rotating machine 25 located in the middle of the centrifugal cylinder 23 can work.

[0034] Example 2, please refer to Figures 1-7The application provides a technical scheme: on the basis of example one, the buffer component 3 comprises a pressure sensing side plate 31, both ends of the pressure sensing side plate 31 are fixedly connected with spring insertion rods 32, when the pressurizing top plate 21 has an upward trend along the inner wall of the solid frame body 11, the two sides of the pressurizing top plate 21 push the spring insertion rods 32 upward, and then the spring insertion rods 32 limit the pressurizing top plate 21, the lower surfaces of the pressure sensing side plates 31 are uniformly provided with fixed connecting rods 33, the upper surfaces of the pressure sensing side plates 31 are rotatably connected with arc-shaped connecting plates 34, one end, away from the pressure sensing side plate 31, of the arc-shaped connecting plate 34 is inserted into the inner wall of the arc-shaped blocking shell 35 through a round head insertion rod, so that the arc-shaped connecting plate 34 can slide along the outer surface of the arc-shaped blocking shell 35 under the guidance of the inner wall of the arc-shaped blocking shell 35, one side, away from the pressure sensing side plate 31, of the arc-shaped connecting plate 34 is rotatably connected with the arc-shaped blocking shell 35, the inner walls of the arc-shaped blocking shell 35 are symmetrically provided with built-in spring bands 36, and the built-in spring bands 36 are used for limiting the sliding distance of the two arc-shaped connecting plates 34, so that the rising height of the arc-shaped blocking shell 35 is limited. The number of the buffer components 3 is two, the bottom of the spring insertion rod 32 is fixedly connected with one side of the surface of the pressurizing top plate 21, the bottom end of the fixed connecting rod 33 is fixedly connected with the upper surface of the solid frame body 11, the number of the arc-shaped blocking shell 35 is one, and the lower surface of the arc-shaped blocking shell 35 is extruded with the outer surface of the centrifugal cylinder 23.

[0035] The power component 5 comprises a supporting connecting plate 51, the bottom end of the supporting connecting plate 51 is fixedly connected with a shock-absorbing plate 52, the lower surface of the shock-absorbing plate 52 is rollingly connected with ground rolling wheels 53, both ends of the ground rolling wheels 53 are rotatably connected with rotor motors 54, and the upper surface of the rotor motor 54 is fixedly connected with a protective supporting plate 55. The number of the power component 5 is two, the number of the ground rolling wheels 53 is four, one end, away from the rotor motor 54, of the protective supporting plate 55 is slidingly connected with one side of the surface of the solid frame body 11, the outer surface of the ground rolling wheel 53 is in contact with the ground, and the top of the supporting connecting plate 51 is fixedly connected with the inner cavity of the solid frame body 11.

[0036] When the pressurizing top plate 21 has an upward movement trend, the two spring insertion rods 32 limit and buffer the pressurizing top plate 21, and the centrifugal cylinder 23 also straightly rises, at this time, the outer surface of the centrifugal cylinder 23 is in contact with the inner wall of the arc-shaped blocking shell 35 directly above, and then pushes the arc-shaped blocking shell 35 to rise, but when the arc-shaped blocking shell 35 rises, the two arc-shaped connecting plates 34 slide downward along the outer surface of the arc-shaped blocking shell 35 while resisting the movement of the arc-shaped blocking shell 35 under the traction of the built-in spring band 36, and the spring potential energy accumulated by the built-in spring band 36 and the spring insertion rod 32 increases the impact effect of the impact block 16 when the impact block 16 moves to impact the ground next time.

[0037] Since the device moves on the unfinished ground, the ground may not be smooth enough, at this time, the ground roller 53 rolls on the ground, and the ground roller 53 is prone to bumping, so the protection plate 55 can slide slightly along the outer surface of the solid frame body 11, thereby reducing the vibration force received by the rotor motor 54. In general, the protection plate 55 will press the rotor motor 54 downward, and then enable the ground roller 53 to support the solid frame body 11, so that the lower surface of the solid frame body 11 is at a distance from the ground, avoiding friction of the solid frame body 11 on the ground.
