Description

Technical Field

[0001] The invention belongs to the technical field of engineering equipment, and particularly relates to an automatic bridge blocking device. Background Art

[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly.

[0003] During the curing stage after the concrete pouring of the bridge is completed, blocking is required. The traditional blocking methods are isolation piles or manual guarding. Manual guarding causes a waste of human resources, and due to cost issues, the gaps between the isolation piers are usually large. For this reason, Chinese Patent CN221218605U discloses an automatic bridge blocking device, which relates to the field of bridges. The automatic bridge blocking device includes a main pile. A rotation blocking block is fixedly connected to the inner surface of the main pile. A spring is fixedly connected to the outer surface of the main pile. A blocking baffle is fixedly connected to the outer surface of the spring away from the main pile. A sleeve is slidably connected to the outer surface of the main pile. A threaded rod is threadedly connected to the inner surface of the sleeve. For this automatic bridge blocking device, when starting the motor, the motor drives the threaded rod to rotate, so that the sleeve threadedly connected thereto is lifted under the block of the pressure chute, so that the sleeve disengages from the lower end of the main pile, and the spring pops out the blocking baffle. The rotation of the threaded rod also drives the rotation of the threaded sleeve, so that the stabilizing rod descends and pierces into the roadbed that is not completely solidified under the block of the rotation blocking block, achieving the purpose of filling the gap between the isolation piles and automatically fixing in the roadbed, and solving the problems of too large gaps between the traditional baffles and cumbersome installation.

[0004] In the above structure, the blocking device is fixed by piercing the stabilizing rod into the bridge deck. However, when the span of the blocking device is different, different piercing depths are required. For example, when the span of the blocking device is large, when the end of the blocking device is stressed, the distance from the fixed point formed by piercing is far, and the moment is large. At this time, the stabilizing rod needs to penetrate deeper into the cement ground. However, in the above structure, the piercing depth cannot be adjusted according to the actual situation, and the fixing effect is insufficient. For this reason, an automatic bridge blocking device with adjustable piercing depth and good fixing effect is needed. Summary of the Invention

[0005] To solve the above problems existing in the prior art, the present invention provides an automatic bridge blocking device, which has the characteristics of adjustable piercing depth and good fixing effect.

[0006] The object of the present invention can be achieved by the following technical solutions:

[0007] An automatic bridge-blocking device includes a main body, which includes a fixed column, a driver, and two intercepting rods. The side of the main body is symmetrically provided with hinge shafts, and the two intercepting rods are respectively arranged at the hinge shafts. The fixed column is telescopic, and the end of the fixed column away from the main body converges to form a tip.

[0008] It further includes a control module, which is used to read the angle of the intercepting rod. When the angle of the intercepting rod exceeds the threshold, the control module increases the extension distance of the fixed column, and when the angle of the intercepting rod is lower than the threshold, the control module decreases the extension distance of the fixed column.

[0009] As a preferred technical solution of the present invention, the control module is used to read the angle a of the intercepting rod, and the control module designates the extension distance of the fixed column as s, where s = a / a0 × c, and a0 and c are constants input in advance.

[0010] As a preferred technical solution of the present invention, it further includes a cement hardness detector electrically connected to the control module. The cement hardness detector is used to detect the cement hardness and upload it to the control module. When the cement hardness exceeds the threshold, the control module downward corrects the extension distance of the fixed column, and when the cement hardness is low, the control module upward corrects the extension distance of the fixed column.

[0011] As a preferred technical solution of the present invention, the cement hardness detector is used to detect the cement hardness y and upload it to the control module. The control module designates the extension distance of the fixed column as s × A1, where A1 = y / y0 × d, and d and y0 are constants input in advance.

[0012] As a preferred technical solution of the present invention, it further includes a wear detector electrically connected to the control module. The wear detector is used to detect the wear degree and upload it to the control module. When the wear degree increases, the control module upward corrects the extension distance of the fixed column.

[0013] As a preferred technical solution of the present invention, the wear detector is used to detect the wear degree m and upload it to the control module. The control module designates the extension distance of the fixed column as s × A1 × A2, where A2 = log(m × 10 / L) + 2, and l is the axial length of the fixed column.

[0014] As a preferred technical solution of the present invention, it further includes an inclination sensor, which is used to detect the inclination angle of the main body and upload it to the control module. The control module judges whether the inclination angle exceeds the threshold and issues an alarm when it exceeds the threshold.

[0015] As a preferred technical solution of the present invention, it further includes a control panel, which is used to input the values of L, d, and y0.

[0016] The beneficial effects of the present invention are:

[0017] (1) By enabling the control module to increase the extended distance of the fixed column when the angle of the interception rod exceeds the threshold, and to decrease the extended distance of the fixed column when the angle of the interception rod is lower than the threshold. When the rotation angle of the interception rod is large and the fixed column needs to penetrate deeper into the cement ground, the penetration depth of the fixed column is increased; when the rotation angle of the interception rod is small and the fixed column does not need to penetrate deeper into the cement ground to reduce damage to the road surface, the penetration depth of the fixed column is decreased;

[0018] (2) By enabling the control module to correct the extended distance of the fixed column downward when the cement hardness exceeds the threshold, and to correct the extended distance of the fixed column upward when the cement hardness is low. When the concrete hardness is high, the fixed column inserted into it can be fixed more firmly, and when the fixed column is severely worn, the penetration depth is corrected downward; when the concrete hardness is low, the fixing degree of the fixed column inserted into it is small, and when the wear of the fixed column is small, the penetration depth is corrected upward;

[0019] (3) By enabling the wear detector to detect the degree of wear and upload it to the control module, the control module corrects the extended distance of the fixed column upward when the degree of wear increases, and when the fixed column is worn and shorter than the extended length required by the control module instruction, the extended distance is corrected upward to re-match the extended length of the instruction, ensuring the extended length and fixing effect.

[0026] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention.

[0027] Please refer to Figures 1-3, an automatic bridge-blocking device, comprising a main body 1, the main body 1 including a fixed column 3, a driver, and two intercepting rods 2. The side surface of the main body 1 is symmetrically provided with hinge shafts, and the two intercepting rods 2 are respectively arranged at the hinge shafts. The fixed column 3 is telescopic, and the end of the fixed column 3 away from the main body 1 converges to form a tip;

[0028] Specifically, the main body 1 is generally a hollow cylindrical structure. In this embodiment, the main body 1 is generally a hollow cylindrical structure. The hollow cylindrical structure has two bottom surfaces, a side surface, and an inner cavity formed by being surrounded. One of the bottom surfaces of the main body 1 is hollowed out. At this time, the inner cavity of the main body 1 structure communicates with the outside. The fixed column 3 is slidably arranged in the main body 1, and a part of the fixed column 3 is located inside the inner cavity of the main body 1, and a part is located outside the inner cavity. The fixed column 3 can move along the axis of the cylindrical main body 1. The tip of the fixed column 3 away from the main body 1 outside the inner cavity converges to form a tip. At the same time, the fixed column 3 at least includes a driver and a supporting transmission structure. In this embodiment, the driver and the transmission structure ensure that the fixed column 3 can move along the axis of the main body 1 and rotate around its own axis during the movement;

[0029] At the same time, two hinge shafts are provided on the side surface of the cylindrical main body 1. The axes of the two hinge shafts are symmetric about the axis of the main body 1 and are both perpendicular to the axis of the main body 1. Intercepting rods 2 are respectively arranged on the two hinge shafts. Taking the plane where the axis of the main body 1 is located as the reference plane, at this time, the intercepting rods 2 can rotate within the reference plane. When the intercepting rods 2 rotate to be close to the side surface of the main body 1, the whole device is in a cylindrical shape, which is convenient for storage. When the intercepting rods 2 rotate to be perpendicular to the side surface of the main body 1, the intercepting rods 2 extend out of the main body 1 to the maximum extent and can play the role of blocking;

[0030] During use, when it is necessary to arrange bridge blocking, several devices are arranged on the bridge deck. The operator or an external device presses on the device and applies a force to the device towards the bridge deck. The driver of the fixed column 3 is activated, driving the rotation of the axis of the fixator while extending out of the main body 1. The tip formed by the convergence of the fixed column 3 penetrates into the bridge deck at this time, completing the penetration of the fixed column 3 into the bridge deck. The fixed column 3 penetrating into the bridge deck provides support and fixation for the automatic bridge-blocking device to prevent the device from shaking. Subsequently, the two intercepting rods 2 rotate along the hinge shafts connected to them, so that the blocking range of the bridge-blocking device is extended. After rotating in place, the blocking of both ends of the blocking line is completed, and the blocking is completed.

[0031] After the blocking rod 2 rotates into place during the above-mentioned use process, when the unfolding span of the blocking device is large, the end of the blocking device is stressed, and the stress point is far from the fixed point formed by the fixed column 3 piercing into the road surface. The moment of prying the fixed point is large. At this time, the fixed column 3 needs to penetrate deeper into the cement ground. However, in the above structure, the penetration depth cannot be adjusted according to the actual situation, and the fixing effect is insufficient. Therefore, it also includes a control module. The control module is used to read the angle of the blocking rod 2. When the angle of the blocking rod 2 exceeds the threshold, the control module increases the extension distance of the fixed column 3, and when the angle of the blocking rod 2 is lower than the threshold, the control module decreases the extension distance of the fixed column 3;

[0032] Specifically, the control module is used to read the angle α of the blocking rod 2. The control module designates the extension distance of the fixed column 3 as s, where s = α / α0×c, and α0 and c are constants input in advance;

[0033] When the control module instructs the blocking rod 2 to rotate along the hinge axis, the control module adjusts the rotation angle of the hinge axis according to the program input in advance by itself or the instruction of the operator. At the same time, the control module reads the recorded rotation angle of the execution, and obtains the rotation angle α of the blocking rod 2 in the current blocking task. In this embodiment, α represents the angle between the axis line of the blocking rod 2 and the axis line of the main body 1;

[0034] When α is large, it means that the rotation angle of the blocking rod 2 is large and the unfolding span is large. The fixed column 3 needs to penetrate deeper into the cement ground. At this time, the value of s = α / α0×c is large. When the control module instructs the extension distance of the fixed column 3 to be designated as s, when the rotation angle of the blocking rod 2 is large and the fixed column 3 needs to penetrate deeper into the cement ground, the penetration depth of the fixed column 3 is increased;

[0035] Similarly, when α is small, it means that the rotation angle of the blocking rod 2 is small and the unfolding span is small. When the penetration depth of the fixed column 3 is too deep, it will cause greater damage to the road surface. Therefore, when it is not necessary to penetrate the fixed column 3 deeper into the cement ground, the penetration depth needs to be reduced. At this time, the value of s = α / α0×c is small. When the control module instructs the extension distance of the fixed column 3 to be designated as s, when the rotation angle of the blocking rod 2 is small and it is not necessary to penetrate the fixed column 3 deeper into the cement ground to reduce the damage to the road surface, the penetration depth of the fixed column 3 is reduced;

[0036] By making the control module increase the extension distance of the fixed column 3 when the angle of the blocking rod 2 exceeds the threshold and decrease the extension distance of the fixed column 3 when the angle of the blocking rod 2 is lower than the threshold, when the rotation angle of the blocking rod 2 is large and the fixed column 3 needs to penetrate deeper into the cement ground, the penetration depth of the fixed column 3 is increased. When the rotation angle of the blocking rod 2 is small and it is not necessary to penetrate the fixed column 3 deeper into the cement ground to reduce the damage to the road surface, the penetration depth of the fixed column 3 is reduced.

[0037] When blocking different bridge decks, the concrete hardness of different bridge decks is different. When the concrete hardness is relatively large, the fixing column 3 inserted into it can be fixed more firmly. However, inserting into harder concrete will cause greater wear on the fixing column 3, and too large an insertion depth will lead to a decrease in the service life of the fixing column 3. At this time, it is necessary to appropriately correct the insertion depth downward. When the concrete hardness is relatively small, the fixing degree of the fixing column 3 inserted into it is relatively low, and the wear on the fixing column 3 during the insertion process is relatively small. Therefore, it also includes a cement hardness detector electrically connected to the control module. The cement hardness detector is used to detect the cement hardness and upload it to the control module. The control module corrects the extended distance of the fixing column 3 downward when the cement hardness exceeds the threshold, and corrects the extended distance of the fixing column 3 upward when the cement hardness is relatively low;

[0038] In this embodiment, the cement hardness detector is used to detect the cement hardness y and upload it to the control module. The control module designates the extended distance of the fixing column 3 as s×A1, where A1 = y / y0×d, and d and y0 are constants input in advance;

[0039] When the cement hardness y is relatively large, it is necessary to appropriately correct the insertion depth downward. At this time, the value of A1 = y / y0×d is relatively small, and s×A1 is relatively small, completing the downward correction of the insertion depth when the cement hardness is relatively large;

[0040] When the cement hardness y is relatively small, it is necessary to appropriately correct the insertion depth upward. At this time, the value of A1 = y / y0×d is relatively large, and s×A1 is relatively large, completing the upward correction of the insertion depth when the cement hardness is relatively small;

[0041] By enabling the control module to correct the extended distance of the fixing column 3 downward when the cement hardness exceeds the threshold and correct the extended distance of the fixing column 3 upward when the cement hardness is relatively low, when the concrete hardness is relatively large, the fixing column 3 inserted into it can be fixed more firmly, and when it causes greater wear on the fixing column 3, the insertion depth is corrected downward. When the concrete hardness is relatively low, the fixing degree of the fixing column 3 inserted into it is relatively small, and when the wear on the fixing column 3 is relatively small, the insertion depth is corrected upward.

[0042] In the above process, the control module instructs the fixing column 3 to extend a certain distance to achieve the effect of inserting into the road surface. However, when the fixing column 3 is worn, after the control module gives an instruction to extend a certain distance, the actual reached distance of the worn fixing column 3 is less than the predetermined distance given by the instruction. When the instruction to correct the extended distance is not performed, it will cause the extended distance of the fixing column 3 to be relatively short and the fixing effect to be insufficient. Therefore, it also includes a wear detector electrically connected to the control module. The wear detector is used to detect the wear degree and upload it to the control module. The control module corrects the extended distance of the fixing column 3 upward when the wear degree increases;

[0043] Specifically, the wear detector is used to detect the wear degree m and upload it to the control module. The control module specifies the extension distance of the fixed column 3 as s×A1×A2, where A2 = log(m×10 / L) + 2, L is the axial length of the fixed column 3, 0 ≤ m ≤ 0.1L. When m = 0.1L, the control module stops the operation and issues an alarm.

[0044] When 0 ≤ m ≤ 0.01L, it means that there is no wear or the wear degree is slight, and no correction is required. At this time, the value of A2 = log(m×10 / L) + 2 is 1. When the control module specifies the extension distance of the fixed column 3 as s×A1×A2, the extension distance of the fixed column 3 is equal to the value of s×A1, completing the non-correction of the extension distance when there is no wear or the wear degree is slight.

[0045] When m is small, it means that the wear degree is small. At this time, there is no need to make a large correction to the extension distance. At this time, the value of A2 = log(m×10 / L) + 2 is small. When the control module specifies the extension distance of the fixed column 3 as s×A1×A2, a small correction to the extension distance is completed when there is a certain amount of wear but the wear degree is low.

[0046] When m is large, it means that the wear degree is large. At this time, a large correction to the extension distance is required. At this time, the value of A2 = log(m×10 / L) + 2 is large. When the control module specifies the extension distance of the fixed column 3 as s×A1×A2, that is, when there is a certain amount of wear and the wear degree is large, a large correction to the extension distance is made.

[0047] At the same time, when the wear degree changes from a small degree to a large degree, upwardly correcting the extension distance has a more obvious effect on improving the fixing effect and will not affect the equipment. At this time, for the extension distance correction value that increases with the wear degree, it is necessary to increase the upward change rate, so as to ensure the fixing effect as much as possible when the wear degree increases.

[0048] When the wear degree approaches the upper limit of 0.1L, continuously increasing the correction value will cause the fixed column 3 to extend to the upper limit of the stroke. At this time, the length of the fixed column 3 inside the main body 1 is short, the contact surface between the fixed column 3 and the main body 1 is small, and the fixing effect on the main body 1 is reduced. At this time, there is no need to increase the upward change rate of the correction value.

[0049] For the function f(m) = log(m×10 / L) + 2, when m is less than 0.05L, the function change rate is large. When m is greater than 0.05L, the function change rate decreases, completing the increase of the upward change rate of the correction value when the wear degree changes from a small degree to a large degree, and stopping increasing the upward change rate of the correction value when the wear degree approaches the upper limit of 0.1L.

[0050] In the above structure, although the fixed column 3 is provided and the extension distance of the fixed column 3 is controlled, however, in some cases, the blocking device still has a probability of tilting, which affects the blocking effect. Therefore, an inclination sensor is further included. The inclination sensor is used to detect the inclination angle of the main body 1 in real time and upload the inclination angle to the control module at a frequency of once per second. The control module determines whether the inclination angle exceeds a threshold value. When it exceeds the threshold value, it means that tilting has occurred. At this time, the control module issues an alarm through the sound and light alarm provided on the main body 1.

[0051] To facilitate the input of the values of L, d, and y0, a control panel electrically connected to the control module is further included. The control panel is used to input the values of L, d, and y0.

[0052] The working principle and usage process of the present invention:

[0053] When in use, when it is necessary to arrange bridge blocking, several devices are arranged on the bridge deck. The operator or an external device presses on the device to apply a force towards the bridge deck to the device. The driver of the fixed column 3 is activated, driving the rotation of the axis of the fixator while extending out of the main body 1. The tip formed by the convergence of the fixed columns 3 then penetrates into the bridge deck at this time, completing the penetration of the fixed column 3 into the bridge deck. The fixed column 3 penetrating into the bridge deck provides support and fixation for the automatic bridge blocking device to prevent the device from shaking. Subsequently, the two intercepting rods 2 rotate along the hinge axis connected thereto, so that the blocking range of the bridge blocking device is extended. After rotating in place, the blocking of both ends of the blocking line is completed, and the blocking is completed.
