Description

Technical Field

[0001] The invention relates to the technical field of road construction equipment, and in particular provides a roadbed rolling times statistics system. Background Art

[0002] Road rollers are widely used in road construction or road maintenance. Roads are usually divided into base layers and surface layers. During road construction or road maintenance, after the base layer construction is completed, it is necessary to lay materials for forming the surface layer on the base layer and compact the materials by a road roller. During the surface layer forming process, the road roller needs to roll the materials many times to compact the materials, thereby ensuring the quality of the road. For example, after the surface layer material is laid, the road roller needs to move back and forth repeatedly in one direction to reduce. During the rolling process, the roller operator is prone to forget or misremember the number of rolling times, resulting in insufficient rolling times. When the number of rolling times is insufficient, the materials constituting the road are not compacted, resulting in poor road quality. Therefore, in the prior art, a technology for monitoring the number of rolling times of the road roller through satellite signals has been developed. For example, the invention patent with the announcement number CN113737614B and the name of a road base unmanned driving group rolling system can obtain the number of rolling times of the road roller through Beidou monitoring of the road roller to avoid the problem of insufficient rolling times.

[0003] However, in underground construction environments such as tunnels, it is difficult for satellite signals to monitor the roller, so it is impossible to count the number of times the roadbed is rolled, and operators still need to perform manual counting. Therefore, there is still a problem in underground construction environments such as tunnels that the number of times the roadbed is rolled cannot be accurately monitored, which needs to be solved urgently. Summary of the invention

[0004] The invention provides a roadbed rolling times counting system, which is used to solve the problem that the rolling times of a road roller are easily misremembered, resulting in insufficient rolling times.

[0005] The technical solution of the present invention is as follows:

[0006] A roadbed rolling times counting system includes two positioning piles and a counting module. A positioning pile is respectively arranged at both ends of the rolling path of a roller. The counting module is arranged on the roller. The positioning pile includes a signal transmitter. The counting module includes a counter, a controller and a signal receiver. The signal receiver and a display are respectively electrically connected to the controller. The signal receiver is used to receive a signal sent by the signal transmitter. When the signal receiver enters the signal radiation range of the signal transmitter, the controller controls the counter to count once.

[0007] In this solution, the counting module is set on the roller, and the counting module moves with the roller. When the roller moves near the positioning pile, the counting module receives the signal from the positioning pile, and then the counting module will count. The number of times the roller rolls is counted through the cooperation of the counting module and the positioning pile, which is not restricted by the external network environment and can be applied to construction environments without a network. In addition, the counting module will count when it enters the signal radiation range of the positioning pile, which can ensure that the roller will only count once when it approaches the positioning pile, avoiding repeated counting and ensuring that the counted number of rolls is accurate and reliable.

[0008] Preferably, the signal radiation range of the signal transmitter is circular in shape.

[0009] In this solution, the circular range can evenly provide signals to the surroundings, so that one positioning pile can cooperate with multiple rollers at the same time, and multiple rollers can be operated at the same time, thereby improving the roadbed rolling efficiency.

[0010] In order to solve the problem that the position of the positioning pile is not easy to observe, the positioning pile also includes a positioning light, which is arranged on the top of the positioning pile and is used to display the position of the positioning pile.

[0011] In this solution, the position of the positioning pile can be displayed by a positioning light, so the roller operator can more easily see the position of the positioning pile and can more accurately determine the end point of the rolling path based on the position of the positioning pile, thereby controlling the movement of the roller.

[0012] In order to solve the problem that the rolling range does not overlap during the reciprocating rolling process of the roller, resulting in insufficient rolling times in some areas of the roadbed and poor roadbed quality, an indicator light sleeve is also provided. The indicator light sleeve includes a sleeve and multiple indicator lights. Each indicator light is respectively arranged in the sleeve. The sleeve is connected to the positioning pile. The indicator light is used to emit an indicator light beam. Each indicator light beam forms a light spot on the ground. Each light spot coincides with the boundary of the rolling path and is used to indicate the boundary of the rolling path.

[0013] In this solution, the indicator light sleeve is fixed to the positioning pile, and the roller operator can judge the rolling path by the light spots. The operator can use the light spots as a reference to control the roller's wheel rim to move along the line connecting the light spots, so that the roller's reciprocating rolling range is the same, ensuring that the rolling times at each position of the roadbed are the same, thereby ensuring the quality of the roadbed.

[0014] In an actual construction environment, the location of the positioning piles will be limited by the site, so the placement of the positioning piles may be different, which will lead to different positions of the indicator light sleeves relative to the rolling path. When the indicator lights are at different positions relative to the rolling path, the light spots cannot completely coincide with the boundaries of the rolling path. To this end, the positioning piles are provided with positioning rods, and the sleeves include a plurality of sleeves, each sleeve is axially stacked to form a sleeve, each sleeve is provided with an indicator light, and the sleeve is sleeved on the positioning rod, and the sleeve is rotatably connected to the positioning rod.

[0015] In this solution, since each ring can rotate relative to the positioning rod, each ring can be rotated separately to adjust the position of the light spot formed by the indicator light on each ring shining on the ground, so that each light spot can form a straight line, and the straight line coincides with the boundary of the rolling path.

[0016] In order to solve the problem that each ring needs to power the indicator light, each ring needs to be connected to the power supply separately during use, which causes cumbersome operation. For this reason, the positioning pile is provided with a conductive ring, and the two end faces of each ring are also provided with conductive rings, and the conductive rings are used to conduct electricity between the rings.

[0017] In this solution, the conductive ring of the ring at the bottom is connected to the conductive ring on the positioning pile, and the conductive ring on the positioning pile can supply the electric energy on the positioning pile to the ring, while the remaining rings are connected to the rings at the bottom through the conductive rings, so that the electric energy can be transmitted upward layer by layer. When the rings are installed, each ring is in a state of being connected to the power supply, so that each ring can be used directly, and there is no need to connect each ring separately, which simplifies the operation steps.

[0018] Preferably, the system also includes a laser line projector, which is arranged on the side of the roller and is used to generate a laser line on the ground. The laser line is perpendicular to the drum axis of the roller, and the roller adjusts its direction according to the laser line and the light spot position.

[0019] In this solution, the accuracy of the roller's rolling path can be determined by whether the laser line and the light spot coincide. The laser line provides a reference for the roller operator, making it easier for the operator to make judgments.

[0020] Preferably, the length of the laser line is greater than the distance between any two adjacent light spots.

[0021] In this solution, the laser line will always coincide with a light spot, making it easier for operators to observe whether the laser line deviates from the light spot.

[0022] Beneficial effects of the present invention:

[0023] The present invention counts the number of rolling times of the roller by cooperating with the positioning pile and the counting module. The counting module counts according to the signal sent by the positioning pile. It can be used in an environment without an external network, solving the problem that the number of rolling times cannot be automatically counted due to satellite positioning during tunnel construction.

[0032] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through specific implementation methods of the embodiments of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, the present embodiment 1 provides a roadbed rolling times counting system, including a positioning pile 1 and a counting module 2. The positioning pile 1 includes a signal transmitter, and the signal transmitter continuously sends signals outward to form a circular signal radiation range 6 within a certain range near the positioning pile 1. The counting module 2 is installed on the roller, and when the roller enters the signal radiation range 6 of the positioning pile 1, the counting module 2 records a number.

[0035] A positioning pile 1 is set at each end of the rolling path of the roller. When the roller moves from one end of the rolling path to the other end of the rolling path, the counting module 2 will record a number, indicating that the number of rolling is one. Therefore, two positioning piles 1 and one counting module 2 can constitute a statistical system for counting the number of rolling.

[0036] It should be noted that the counting module 2 may also include multiple counting modules 2, each of which is respectively arranged in a different roller. Because the counting module 2 counts after entering the radiation range of the positioning pile 1, when each counting module 2 enters the radiation range of the positioning pile 1, each counting module 2 counts respectively, thereby recording the number of rolling times of each roller respectively.

[0037] The diameter of the signal radiation range 6 of the positioning pile 1 may be in the range of 8-15 m, and this range may cover most of the highway in the width direction.

[0038] The counting module 2 includes a counter, a controller and a signal receiver. The signal receiver is used to receive the signal sent by the positioning pile 1. When the signal receiver receives the signal, the controller controls the counter to count. The counter can be equipped with a display screen, which can display the number of rolling times counted by the counter, so that the operator of the roller can watch it.

[0039] The controller can be a PLC or a single-chip microcomputer.

[0040] The signal sent by the positioning pile 1 and the signal received by the technical module can be a Bluetooth signal. The power consumption required by the Bluetooth signal is very small, usually between 1-100 mW, which can ensure that the positioning pile 1 and the counting module 2 can be used for a long time.

[0041] like Figure 2 As shown, the positioning pile 1 also includes a pile body 11, a positioning light 13 and an indicator light cover 14, wherein the signal transmitter, the positioning light 13 and the indicator light cover 14 are all arranged on the pile body 11, and the pile body 11 plays a role in supporting and fixing the signal transmitter, the positioning light 13 and the indicator light cover 14.

[0042] The positioning lamp 13 is arranged on the top of the pile body 11, and the function of the positioning lamp 13 is to display the position of the positioning pile 1. The light color of the positioning lamp 13 can be red, green or other colors for easy identification.

[0043] The function of the indicator light sleeve 14 is to emit light to the ground. When the light hits the ground, a light spot 4 will be left on the ground. The indicator light sleeve 14 will emit multiple rays of light to the ground, and the light spot 4 formed by each ray of light will coincide with the boundary of the rolling path. The rolling path of the roller is usually a straight path. During the rolling process, the roller only needs to move back and forth in a constant direction, which can improve the rolling efficiency. Therefore, the boundary of the rolling path is usually a straight line, and the line connecting the light spots 4 is also a straight line. When operating the roller, the edge of the roller's drum coincides with the light spot 4, which can ensure that the roller is walking on the correct rolling path. This can solve the problem that the actual rolling range is different from the planned rolling range due to errors in the direction of the roller during its movement, ensuring that the rolling range is accurate, thereby ensuring the quality of the roadbed.

[0044] Under normal conditions, each light spot 4 needs to be connected into a straight line, and the positioning pile 1 can be placed on the straight line. However, when the positioning pile 1 cooperates with multiple counting modules 2, the positioning pile 1 obviously cannot be placed on the boundary of each rolling path. Therefore, the indicator light sleeve 14 includes multiple rings 141, each ring 141 is coaxial and rotatably connected to each other, and each ring 141 is respectively provided with an indicator light 142. By rotating each ring 141, the indicator lights 142 on each ring 141 can be relatively rotated, changing the angle of the indicator lights 142 on each ring 141. After changing the angle of the indicator light 142, the position of the light spot 4 formed by each indicator light 142 on the ground can be changed, so by rotating the ring 141, each light spot 4 can be made to coincide with the rolling light.

[0045] It should be noted that the light emitted by the indicator light 142 on each collar 141 has an angle with the horizontal plane, and the angles of each light with the horizontal plane are different, so that the light spot 4 formed on the ground by each light can reach the middle of the rolling path. The light spot 4 formed on the ground by the indicator light sleeve 14 on one positioning pile 1 can cover the middle of the rolling path, and the boundary of the entire rolling path can be covered by two positioning piles 1 located at both ends of the rolling path.

[0046] The spacing between adjacent light spots 4 can be 5-10m. At this spacing, the directional deviation of the roller is very small, so it can be adjusted in time when passing the next light spot 4. When the length of the rolling path is 100m, only 5-10 rings 141 need to be set on the two positioning piles 1. When the construction situation is different, the length of the rolling path will also change. At this time, the number of rings 141 can be increased or decreased to adapt to different construction situations.

[0047] The indicator lights 142 provided on each collar 141 may be laser lights. The light beam generated by the laser lights is a linear light beam, which facilitates the formation of light spots 4 on the boundaries of the rolling path.

[0048] It should be noted that the use of light spot 4 to define the roller rolling path is suitable for relatively dark environments such as tunnel construction. When the ambient light is relatively dark, the operator can easily determine the position of light spot 4 and thus control the movement of the roller according to the position of light spot 4.

[0049] The indicator light cover 14 needs to be fixed to the positioning pile 1 , and a positioning rod 15 is provided on the positioning pile 1 . The indicator light cover 14 is sleeved on the positioning rod 15 , and the indicator light cover 14 and the positioning rod 15 are rotatably connected.

[0050] A plurality of positioning rods 15 may be provided on the positioning pile 1. When the positioning pile 1 needs to cooperate with a plurality of counting units, it is also necessary to separately configure an indicator light sleeve 14 for the roller corresponding to each counting unit, and each indicator light sleeve 14 corresponds to a different rolling path.

[0051] like Figure 3 and Figure 4 As shown, a shoulder is provided at the bottom of the positioning rod 15, and the positioning rod 15 is vertically arranged. Two conductive rings are provided on the upper end surface of the shoulder. The two conductive rings are coaxially arranged with the positioning rod 15, and the two conductive rings are connected to the two poles of the power supply respectively. Conductive rings are also provided on the two end surfaces of the collar 141 respectively. When the collar 141 is connected to the positioning rod 15, the two conductive rings on the ground of the collar 141 fit with the two conductive rings on the positioning rod 15, so that the collar 141 is connected to the power supply, so that the indicator light 142 on the collar 141 is powered on and works. When the collar 141 is connected to the collar 141, the collar 141 located on the upper side is also electrically connected to the collar 141 located on the lower side through the conductive ring, so that the collar 141 can transmit electric energy through the conductive ring, thereby powering all the collars 141. The conductive ring can make the collar 141 always in the powered state during the rotation process, and when the collar 141 is rotated to change the angle of the indicator light 142, the indicator light 142 can continue to work.

[0052] like Figure 5 As shown, a laser line projector 3 can also be set on the side of the roller, and a laser line 5 is generated on the ground by the laser line projector 3, and the axis of the laser line 5 is perpendicular to the axis of the roller. The two ends of the laser line 5 extend to the front and rear sides of the roller respectively. When the roller moves forward or backward, the relative position of the laser line 5 and the light spot 4 can be used to judge whether the roller's rolling path is accurate. The length of the laser line 5 is greater than the length of the roller and the distance between two adjacent light spots 4.
