Description

Technical Field

[0001] The invention belongs to the technical field of concrete leveling equipment, in particular to a novel coarse aggregate ultra-high performance concrete bridge deck prefabrication trolley. Background Art

[0002] Ultra-high performance concrete, also known as reactive powder concrete, is the most innovative cement-based engineering material in the past three decades, achieving a major leap in the performance of engineering materials. The design theory of ultra-high performance concrete is the maximum packing density theory, in which particles of different particle sizes of its constituent materials are packed in the most compact proportion, that is, the gaps between millimeter-sized particles are filled with micron-sized particles, and the gaps between micron-sized particles are filled with submicron-sized particles.

[0003] During the prefabrication of bridge decks, after the ultra-high performance concrete is paved on the formwork, a row vibrator is used to vibrate the concrete to make the concrete compact and avoid bubbles inside the concrete. A flat plate vibrator is then used to re-vibrate and level the surface of the bridge deck, thereby improving the quality of the prepared bridge deck. Currently, during the prefabrication of bridge decks, a movable trolley is usually used to drive the flat plate vibrator to move, so that the flat plate vibrator moves slowly along the surface of the bridge deck, thereby re-vibrating and leveling the surface of the bridge deck, thereby ensuring the quality of the prefabricated bridge deck.

[0004] Existing movable trolleys are usually mounted on travel drive wheels and auxiliary support wheels, so that they move in the horizontal direction under the action of the friction force generated by the rotation of the travel drive wheels, and then drive the flat plate vibrator to move to re-vibrate and level the surface of the bridge deck; however, due to ground foundation settlement, wear of the travel drive wheels and auxiliary support wheels and other reasons, the bearing surface of the trolley is prone to deviation relative to the horizontal plane. When the deviation is too large, it will cause the surface shape of the prefabricated bridge deck to deviate, affecting the quality of the prefabricated bridge deck. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, the possible deviations of the trolley in various directions are automatically adjusted through the adjustment module to ensure that the working surface of the flat plate vibrator and the bridge deck are parallel to each other and the flat plate vibrator is close to the surface of the bridge deck, so as to achieve good re-vibration and leveling effects on the surface of the bridge deck and ensure the quality of the produced bridge deck.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 10As shown, a novel coarse aggregate ultra-high performance concrete bridge deck prefabricated trolley of the present invention comprises a trolley frame 1, a walking module 11 is installed at the lower end of the trolley frame 1, a mounting plate 2 is installed at the upper end of the trolley frame 1, a driving motor 21 is installed on the mounting plate 2, and an adjustment module and a flat plate vibrator 5 are installed in sequence below the mounting plate 2;

[0040] The adjustment module includes a transverse adjustment mechanism 3 and a longitudinal adjustment mechanism rod 4. The transverse adjustment mechanism 3 adjusts the height difference between the two ends of the trolley frame 1 in the transverse direction T, and the longitudinal adjustment mechanism rod 4 adjusts the height difference between the two ends of the trolley frame 1 in the longitudinal direction P.

[0041] The lateral adjustment mechanism 3 includes an upper frame 31, a lower frame 32 and a hydraulic connecting rod 33. The upper frame 31 is in an L shape, and the lower frame 32 is in an inverted L shape. The hydraulic connecting rod 33 is installed between the horizontal plates of the upper frame 31 and the lower frame 32. The horizontal plate of the lower frame 32 is located above the horizontal plate of the upper frame 31. The upper frame 31 is connected to the mounting plate 2.

[0042] The hydraulic connecting rods 33 are provided in multiple groups, and the hydraulic connecting rods 33 are interconnected;

[0043] The longitudinal adjustment mechanism rod 4 includes a longitudinal axis 41 and a mounting frame 411. Both ends of the longitudinal axis 41 are connected to the plate vibrator 5 through the mounting frame 411. The lower frame 32 is connected to the middle position of the longitudinal axis 41.

[0044] After the ultra-high performance concrete is paved on the formwork platform and row-type vibrated, the staff controls the trolley to move to the formwork platform, and automatically adjusts the inclination and angle of the trolley through the adjustment module to ensure that the working surface of the flat plate vibrator 5 is parallel to the surface of the prefabricated bridge deck. After that, the staff controls the flat plate vibrator 5 to descend and contact the surface of the prefabricated bridge deck, and then drives the flat plate vibrator 5 to re-vibrate and level the surface of the prefabricated bridge deck through the slow movement of the trolley to ensure the quality of the bridge deck.

[0045] At the same time, when the ground foundation settles and the trolley's running wheels wear, resulting in a deviation between the mounting surface on the trolley and the horizontal plane:

[0046] When the ground on both sides of the width direction of the prefabricated bridge deck is not level, so that the heights of the trolley on both sides in the width direction of the bridge deck, i.e., in the transverse direction T, are inconsistent, a plurality of groups of hydraulic connecting rods 33 connected to each other are installed in the transverse adjustment mechanism 3. Since the hydraulic connecting rods 33 are subjected to pressure under the action of the upper frame 31 and the lower frame 32, the hydraulic connecting rods 33 connected to each other are subjected to less pressure on the hydraulic connecting rods 33 on the side with lower height of the trolley and greater pressure on the hydraulic connecting rods 33 on the side with higher height of the trolley according to Pascal's principle, so that the lower frame 32 connected to the upper end of the hydraulic connecting rods 33 is at the same height, thereby ensuring that the working surface of the flat plate vibrator 5 below the adjustment module is parallel to the surface of the prefabricated panel, avoiding deviation between the trolley installation surface and the horizontal plane, resulting in deviation in the surface shape of the produced prefabricated bridge deck, and affecting the quality of the prefabricated bridge deck;

[0047] When the ground in front and behind the length direction of the prefabricated bridge deck is not level, so that the heights of the trolley in the length direction of the bridge deck, i.e., the longitudinal direction P, are inconsistent, the plate vibrator 5 is subjected to the gravity and the plate vibrator 5 is installed on the longitudinal axis 41 in the longitudinal adjustment mechanism rod 4, so that the plate vibrator 5 rotates relative to the longitudinal axis 41, i.e., the plate vibrator 5 maintains a vertical state under the action of gravity, i.e., the working surface of the plate vibrator 5 is parallel to the surface of the bridge deck, so as to ensure the surface shape standard of the produced prefabricated bridge deck and the good quality of the prefabricated bridge deck;

[0048] At the same time, after the adjustment module automatically adjusts the possible skew and offset of the trolley, the staff begins to control the plate vibrator 5 to gradually descend: control the hydraulic connecting rod 33 to gradually retract, so that the lower frame 32 begins to move downward relative to the upper frame 31, so that the working surface of the plate vibration contacts the surface of the bridge deck, and begins to re-vibrate and level the surface of the prefabricated bridge deck to ensure the quality of the produced bridge deck. At the same time, since the plate vibrator 5 is installed on the mounting plate 2 through the adjustment module, and the upper frame 31 and the lower frame 32 are connected by the hydraulic connecting rod 33, after the plate vibrator 5 moves downward and contacts the surface of the bridge deck, it can continue to be pressed downward against the surface of the bridge deck under the action of the hydraulic connecting rod 33, ensuring good re-vibration and leveling effects on the bridge deck, and ensuring good quality of the bridge deck;

[0049] At the same time, the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism rod 4 can automatically adjust and offset the deviations of the trolley in various directions, so as to avoid the ground foundation from settling, deformation and damage, and the wheels of the trolley from wear and damage, which will cause the installation surface on the trolley to deviate from the horizontal plane, and further cause a deviation between the working surface of the flat plate vibrator 5 installed on the trolley and the surface of the prefabricated bridge deck, so that the surface shape of the produced bridge deck does not meet the requirements, affecting the quality of the bridge deck.

[0050] As an embodiment of the present invention, a hinge shaft 331 is installed at the lower end of the hydraulic connecting rod 33, and the hinge shaft 331 is rotatably installed on the horizontal plate of the upper frame 31;

[0051] The mounting frame 411 and the horizontal plate of the upper frame 31 are both installed with a locking mechanism 6, and the locking mechanism 6 locks the hinge shaft 331 and the longitudinal shaft 41;

[0052] The locking mechanism 6 includes a hydraulic cylinder 613, and a contact wheel 61 is installed on the extended end of the hydraulic cylinder 613. The contact wheel 61 is in contact with the hinge shaft 331, and the contact wheels 61 are arranged in pairs and in contact with each other.

[0053] Since the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism rod 4 can automatically adjust and offset the possible deviation of the trolley, it is ensured that the working surface of the flat plate vibrator 5 installed on the trolley is parallel to the surface of the bridge deck. Therefore, when the trolley stops moving and the flat plate vibrator 5 does not move or run, the flat plate vibrator 5 can maintain relative parallelism with the horizontal plane and the surface of the bridge deck under the action of the adjustment module. When the trolley starts moving and the flat plate vibrator 5 starts to re-vibrate and level the surface of the bridge deck, the vibration generated by the flat plate vibrator 5 itself and the inertia and vibration generated by the movement of the trolley are likely to interfere with the adjustment module, causing the adjustment module to deviate from the adjustment of the flat plate vibrator 5 or causing a deviation between the working surface of the flat plate vibrator 5 and the horizontal plane, affecting the quality of the produced bridge deck.

[0054] Therefore, before the trolley moves to the bridge deck and the flat plate vibrator 5 starts to descend, the trolley and the flat plate vibrator 5 are kept stationary for a period of time, so that the adjustment module automatically completes the adjustment and offset of the possible deviation of the trolley, ensures the level of the working surface of the flat plate vibrator 5, and then ensures the quality of the produced bridge deck. After that, the staff controls the locking mechanism 6 to lock the hinge shaft 331 and the longitudinal shaft 41 of the hydraulic connecting rod 33, so as to ensure the stability of the adjustment result of the adjustment module and avoid affecting the quality of the produced bridge deck;

[0055] At the same time, when the locking mechanism 6 is working, the hydraulic cylinder 613 starts to move, so that the extending end of the hydraulic cylinder 613 drives the contact wheel 61 to start extending, so that the contact wheel 61 is in close contact with the surface of the hinge shaft 331 and the longitudinal shaft 41, thereby utilizing the friction between the contact wheel 61 and the contact wheel 61, the contact wheel 61 and the hinge shaft 331, or the contact wheel 61 and the longitudinal shaft 41 to lock the adjustment module, thereby avoiding interference with the automatic adjustment effect of the adjustment module during the movement of the trolley and the operation of the flat plate vibrator 5.

[0056] As an embodiment of the present invention, the areas on the hinge shaft 331 and the longitudinal shaft 41 that contact the contact wheel 61 are roughened, and the surface of the contact wheel 61 is also roughened;

[0057] The surface of the contact wheel 61 is provided with a mounting hole, a clamping block 612 is mounted in the mounting hole 611 through a soft spring, grooves are formed in the roughened areas on the hinge shaft 331 and the longitudinal shaft 41, the clamping block 612 cooperates with the grooves, and the hinge shaft 331 and the longitudinal shaft 41 are magnetic;

[0058] By roughening the area on the hinge shaft 331 and the longitudinal shaft 41 that contacts the contact wheel 61, the friction between the contact wheel 61 and the hinge shaft 331, and between the contact wheel 61 and the longitudinal shaft 41 is relatively large, thereby further improving the locking effect of the locking mechanism 6 on the adjustment module, and preventing the plate vibrator 5 located under the adjustment module from shaking or swinging when the trolley is moving or the plate vibrator 5 is lifting, which affects the normal use of the prefabricated trolley and creates safety hazards;

[0059] At the same time, when the hydraulic cylinder 613 drives the contact wheel 61 to move toward the articulated shaft 331 or the longitudinal shaft 41, the magnetic force on the block 612 on the contact wheel 61 from the articulated shaft 331 or the longitudinal shaft 41 gradually increases. When the contact wheel 61 contacts the articulated shaft 331 or the longitudinal shaft 41, the magnetic attraction force on the block 612 is greater than the elastic force of the soft spring, so that the block 612 extends from the mounting hole 611 and contacts the groove formed in the roughened area on the surface of the articulated shaft 331 or the longitudinal shaft 41. The cooperation between the block 612 and the groove further improves the locking effect of the locking mechanism 6 on the adjustment module, thereby preventing the articulated shaft 331 or the longitudinal shaft 41 from still rotating after being locked, thereby affecting the normal use of the prefabricated trolley and causing safety hazards.

[0060] As an implementation mode of the present invention, the connection directions CL between the lower rack 32 and the upper rack 31 of each group are different;

[0061] Since the vertical plates between the upper frame 31 and the lower frame 32 are aligned with each other, the two sides of the upper frame 31 and the lower frame 32, that is, in the direction perpendicular to the connection line direction CL between the upper frame 31 and the lower frame 32, are in an open state without other vertical plates for support and restriction. Therefore, when the trolley has a deviation from the horizontal plane and the trolley is running, the upper frame 31 and the lower frame 32 are prone to tilt and deformation in the direction perpendicular to the connection line direction CL, resulting in deformation and instability of the structure formed by the upper frame 31, the lower frame 32 and the hydraulic connecting rod 33, that is, affecting the stability of the lateral adjustment mechanism 3 and the adjustment effect of the deviation of the trolley. Therefore, for different The installation angle of the structure composed of the upper frame 31, the lower frame 32 and the hydraulic connecting rod 33 is adjusted so that the connection direction CL of the upper frame 31 and the lower frame 32 in each structure composed of the upper frame 31, the lower frame 32 and the hydraulic connecting rod 33 is different, thereby utilizing the possible deformation, opposite and offset of the skew directions between the structures composed of the upper frame 31, the lower frame 32 and the hydraulic connecting rod 33 with mutually perpendicular connection directions CL to improve the stability of the structure composed of the upper frame 31, the lower frame 32 and the hydraulic connecting rod 33, prevent the structure from being skewed or deformed due to external factors, affect the adjustment effect of the adjustment module on the offset of the trolley, and avoid safety hazards of the adjustment module.

[0062] As an embodiment of the present invention, a connecting groove 34 is provided on the side of the upper frame 31 facing the lower frame 32, a slider 341 is installed in the connecting groove 34, a connecting rope is installed on the slider 341, and the other end of the connecting rope is installed on the side of the horizontal plate of the lower frame 32 facing the upper frame 31;

[0063] The length of the connecting rope is greater than or equal to the distance between the horizontal plate of the lower frame 32 and the upper frame 31;

[0064] When relative movement occurs between the upper frame 31 and the lower frame 32, the lower frame 32 will pull the connecting rope, thereby driving the slider 341 to slide in the connecting groove 34, ensuring that the movement of the lower frame 32 will not be restricted by the connecting rope. At the same time, due to the length limitation of the connecting rope and the two ends of the connecting rope being respectively connected to the upper frame 31 and the lower frame 32, the stability of the structure composed of the upper frame 31 and the lower frame 32 is improved, thereby avoiding or reducing the possibility of excessive skewing or deviation between the upper frame 31 and the lower frame 32, which may cause safety hazards to the prefabricated trolley.

[0065] As an embodiment of the present invention, the connecting rope includes a limiting rope 342 and a signal line 343, an alarm block 344 is installed on the limiting rope 342, a breaking rod 345 is eccentrically installed in the alarm block 344, the limiting rope 342 bypasses the breaking rod 345 in the alarm block 344 to form a bending area, the length of the signal line 343 is equal to the length of the limiting rope 342 on which the alarm block 344 is installed, and the signal line 343 is electrically connected to the alarm;

[0066] Since the limiting rope 342 passes through the alarm block 344 and is blocked by the breaking rod 345 in the alarm block 344, a bending area of ​​the limiting rope 342 appears in the alarm block 344, thereby shortening the length of the limiting rope 342 outside the alarm block 344, that is, the length of the signal line 343 is equal to the length of the limiting rope 342 after the alarm block 344 is installed. At the same time, when the prefabricated trolley is working normally, the breaking rod 345 remains intact, the limiting rope 342 has a bending area in the alarm block 344, the signal line 343 remains electrically connected to the alarm, and the alarm does not operate. When the rotation angle of the hinge shaft 331 of the hydraulic connecting rod 33 is too large, the tension on the limiting rope 342 is relatively large, and the breaking rod 345 in the alarm block 344 breaks, and the limiting rope 342 is straightened again in the bent area within the alarm block 344. At this time, the length of the limiting rope 342 is greater than the length of the signal line 343, so that the signal line 343 breaks, and then the alarm starts to work, so that the staff can handle the trolley in time to ensure that the deviation between the installation surface of the trolley and the horizontal plane is within the range that can be adjusted and offset by the adjustment module, so as to ensure that the trolley can work normally and avoid safety hazards during the operation of the trolley.

[0067] As an embodiment of the present invention, a guide rod 42 is installed on the bracket 51, and the upper end of the guide rod 42 is slidably installed on the mounting frame 411, and there is a gap between the lower end of the mounting frame 411 and the upper end of the bracket 51;

[0068] Since there is a gap between the lower end of the mounting frame 411 and the upper end of the bracket 51, during the downward movement of the flat plate vibrator 5, the flat plate vibrator 5 will first contact the surface of the bridge deck, and then the mounting frame 411 on the longitudinal axis 41 will continue to move downward until the mounting frame 411 and the bracket 51 contact each other, thereby generating a downward squeezing force on the flat plate vibrator 5, ensuring that the flat plate vibrator 5 and the surface of the bridge deck are in contact with each other, ensuring the effect of re-vibrating and leveling the surface of the bridge deck, and ensuring the quality of the produced bridge deck;

[0069] At the same time, since there is a gap between the mounting frame 411 and the bracket 51, and the mounting frame 411 can slide along the guide rod 42, when the flat plate vibrator 5 is lowered, the contact between the flat plate vibrator 5 and the mold platform is relatively buffered, thereby preventing the flat plate vibrator 5 and the mold platform from colliding with each other and causing damage;

[0070] At the same time, the vibration generated by the flat plate vibrator 5 can also be isolated, reducing the influence of the vibration generated by the flat plate vibrator 5 on the adjustment module.

[0071] As an embodiment of the present invention, a counterweight box is installed on the support 51 of the plate vibration, and the counterweight box contains liquid;

[0072] By installing a counterweight box on the bracket 51, the weight near the plate vibrator 5 is increased, so that the center of gravity of the prefabricated trolley is relatively low, the stability of the prefabricated trolley during use is increased, and potential safety hazards are avoided;

[0073] At the same time, the liquid filled in the counterweight box will produce a damping effect, further isolating the vibration generated by the plate vibrator 5 and offsetting the vibration generated during the movement of the trolley, thereby avoiding or reducing the interference of the vibration on the adjustment module, ensuring the adjustment effect of the adjustment module, and further ensuring the quality of the produced bridge deck;

[0074] At the same time, when the deformation and settlement of the ground foundation are too serious, causing the deviation between the mounting surface of the trolley and the horizontal plane to change frequently during the movement of the trolley along the length direction of the bridge deck, in order to temporarily ensure the delay in the production progress of the bridge deck, the staff does not use the locking mechanism 6 to lock the hinge shaft 331 and the longitudinal shaft 41, so that the adjustment module can adjust the deviation between the mounting surface of the trolley and the horizontal plane at any time, and through the added counterweight and the damping effect of the liquid in the counterweight box, it is ensured as much as possible that the working surface of the flat plate vibrator 5 is parallel to the horizontal plane, and it is ensured as much as possible that the vibration of the flat plate vibrator 5 does not affect the adjustment of the adjustment module too much, thereby ensuring the production progress of the bridge deck and the quality of the produced bridge deck.

[0075] The specific workflow is as follows:

[0076] After the ultra-high performance concrete is paved on the formwork platform and row-type vibrated, the staff controls the trolley to move to the formwork platform, and automatically adjusts the inclination and angle of the trolley through the adjustment module. After that, the staff controls the flat plate vibrator 5 to descend and contact the surface of the prefabricated bridge deck, and then drives the flat plate vibrator 5 to re-vibrate and level the surface of the prefabricated bridge deck through the slow movement of the trolley;

[0077] At the same time, when the ground foundation settles and the trolley's running wheels wear, resulting in a deviation between the mounting surface on the trolley and the horizontal plane:

[0078] When the ground on both sides of the prefabricated bridge deck is not level, so that the heights of the trolley on both sides of the bridge deck in the width direction, i.e., in the transverse direction T, are inconsistent, the transverse adjustment mechanism 3 is equipped with a plurality of interconnected hydraulic connecting rods 33, so that the lower frame 32 connected to the upper end of the hydraulic connecting rod 33 is at the same height, ensuring that the working surface of the plate vibrator 5 below the adjustment module is parallel to the surface of the prefabricated panel;

[0079] When the ground in front and behind the prefabricated bridge deck in the length direction is not level, so that the heights of the trolley in the front and rear sides in the length direction of the bridge deck, i.e., in the longitudinal direction P, are inconsistent, the plate vibrator 5 rotates relative to the longitudinal axis 41, and the working surface of the plate vibrator 5 and the surface of the bridge deck are parallel to each other;

[0080] At the same time, after the adjustment module automatically adjusts the possible skew and offset of the trolley, the staff starts to control the plate vibrator 5 to gradually descend: control the hydraulic connecting rod 33 to gradually retract, so that the lower frame 32 starts to move downward relative to the upper frame 31, so that the working surface of the plate vibration contacts the surface of the bridge deck, and the plate vibrator 5 is pressed downward against the surface of the bridge deck;

[0081] At the same time, the lateral adjustment mechanism 3 and the longitudinal adjustment mechanism rod 4 can automatically adjust and offset the deviations of the trolley in various directions.

[0082] Before the trolley moves to the bridge deck and the flat plate vibrator 5 starts to descend, the trolley and the flat plate vibrator 5 are kept stationary for a period of time, so that the adjustment module automatically completes the adjustment and offset of the possible deviation of the trolley to ensure the level of the working surface of the flat plate vibrator 5. After that, the staff controls the locking mechanism 6 to lock the articulated shaft 331 and the longitudinal shaft 41 of the hydraulic connecting rod 33;

[0083] At the same time, when the locking mechanism 6 is working, the hydraulic cylinder 613 starts to move, so that the extended end of the hydraulic cylinder 613 drives the contact wheel 61 to start extending, so that the contact wheel 61 is in close contact with the surface of the hinge shaft 331 and the longitudinal shaft 41, so as to lock the adjustment module by using the friction between the contact wheel 61 and the contact wheel 61, the contact wheel 61 and the hinge shaft 331, or the contact wheel 61 and the longitudinal shaft 41;

[0084] By roughening the area on the hinge shaft 331 and the longitudinal shaft 41 that contacts the contact wheel 61, the friction between the contact wheel 61 and the hinge shaft 331 and the contact wheel 61 and the longitudinal shaft 41 is relatively large, thereby improving the locking effect of the locking mechanism 6 on the adjustment module;

[0085] At the same time, when the hydraulic cylinder 613 drives the contact wheel 61 to move toward the hinge shaft 331 or the longitudinal shaft 41, the magnetic force on the block 612 on the contact wheel 61 from the hinge shaft 331 or the longitudinal shaft 41 gradually increases. When the contact wheel 61 contacts the hinge shaft 331 or the longitudinal shaft 41, the magnetic attraction force on the block 612 is greater than the elastic force of the soft spring, so that the block 612 extends out of the mounting hole 611 and contacts the groove formed in the roughened area on the surface of the hinge shaft 331 or the longitudinal shaft 41.

[0086] The installation angles of the structures composed of different upper frames 31, lower frames 32 and hydraulic connecting rods 33 are adjusted so that the connection directions CL of the upper frames 31 and lower frames 32 in the structures composed of the upper frames 31, lower frames 32 and hydraulic connecting rods 33 are different, thereby utilizing the possible deformation, opposite and offsetting of the skew directions between the structures composed of the upper frames 31, lower frames 32 and hydraulic connecting rods 33 whose connection directions CL are perpendicular to each other to improve the stability of the structures composed of the upper frames 31, lower frames 32 and hydraulic connecting rods 33, and prevent the structures from being skewed or deformed under the influence of external factors;

[0087] When the upper frame 31 and the lower frame 32 move relative to each other, the lower frame 32 pulls the connecting rope, thereby driving the slider 341 to slide in the connecting groove 34. At the same time, due to the limited length of the connecting rope and the two ends of the connecting rope being respectively connected to the upper frame 31 and the lower frame 32, the stability of the structure composed of the upper frame 31 and the lower frame 32 is improved.

[0088] When the prefabricated trolley is working normally, the broken rod 345 remains intact, the limiting rope 342 has a bending area in the alarm block 344, the signal line 343 maintains electrical connection with the alarm, and the alarm does not work. When the deviation between the installation surface of the trolley and the horizontal plane is too large, and the rotation angle of the hinge shaft 331 of the hydraulic connecting rod 33 is too large, so that the tension on the limiting rope 342 is relatively large, the broken rod 345 in the alarm block 344 breaks, and the bending area of ​​the limiting rope 342 in the alarm block 344 is straightened again. At this time, the length of the limiting rope 342 is greater than the length of the signal line 343, so that the signal line 343 breaks, and then the alarm starts to work, so that the staff can deal with the trolley in time;

[0089] Since there is a gap between the lower end of the mounting frame 411 and the upper end of the bracket 51, during the downward movement of the flat plate vibrator 5, the flat plate vibrator 5 will first contact the surface of the bridge deck, and then the mounting frame 411 on the longitudinal axis 41 will continue to move downward until the mounting frame 411 and the bracket 51 contact each other, generating a downward squeezing force on the flat plate vibrator 5;

[0090] At the same time, since there is a gap between the mounting frame 411 and the bracket 51, and the mounting frame 411 can slide along the guide rod 42, when the flat plate vibrator 5 is lowered, the contact between the flat plate vibrator 5 and the mold table is relatively buffered;

[0091] At the same time, the vibration generated by the flat plate vibrator 5 can also be isolated, reducing the impact of the vibration generated by the flat plate vibrator 5 on the adjustment module;

[0092] By installing a counterweight box on the bracket 51, the weight near the plate vibrator 5 is increased, so that the center of gravity of the prefabricated trolley is relatively low;

[0093] At the same time, the liquid filled in the counterweight box will produce a damping effect, further isolating the vibration generated by the plate vibrator 5 and offsetting the vibration generated during the movement of the trolley, thereby avoiding or reducing the interference of the vibration on the adjustment module;

[0094] At the same time, when the deformation and settlement of the ground foundation are too serious, causing the deviation between the mounting surface of the trolley and the horizontal plane to change frequently during the movement of the trolley along the length direction of the bridge deck, in order to temporarily ensure the production progress of the bridge deck, the staff does not use the locking mechanism 6 to lock the hinge shaft 331 and the longitudinal axis 41, so that the adjustment module can adjust the deviation between the mounting surface of the trolley and the horizontal plane at any time, and through the added counterweight and the damping effect of the liquid in the counterweight box, it is ensured as much as possible that the working surface of the flat plate vibrator 5 is parallel to the horizontal plane, and it is ensured as much as possible that the vibration of the flat plate vibrator 5 does not affect the adjustment of the adjustment module too much.
