It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please refer to Figures 1 to 5 at the same time. Now, the intelligent tensioning integrated construction trolley for prestressed beams in building construction projects provided by the present invention will be described. The intelligent tensioning integrated construction trolley for prestressed beams in building construction projects includes a vehicle frame 1, an arc-shaped support plate 3, a driving assembly 5, and an arc-shaped pressing plate 4. A hoisting arm 2 is installed on the vehicle frame 1; the arc-shaped support plate 3 is installed on the vehicle frame 1, and the arc-shaped support plate 3 is rotatably arranged on the vehicle frame 1 with its own axis as the center, and the inner wall of the arc-shaped support plate 3 forms an arc-shaped groove for placing a jack; the driving assembly 5 is installed between the vehicle frame 1 and the arc-shaped support plate 3 and is used to drive the arc-shaped support plate 3 to rotate; the arc-shaped pressing plate 4 is arranged parallel to the axis of the arc-shaped support plate 3 at an interval, and the arc-shaped pressing plate 4 is rotatably arranged on the vehicle frame 1 with its own axis as the center, and the arc-shaped pressing plate 4 can be rotated above the arc-shaped support plate 3 to limit the jack inside the arc-shaped support plate 3.

[0032] Compared with the prior art, the intelligent tensioning integrated construction trolley for prestressed beams in building construction projects provided in this embodiment is provided with a vehicle frame 1, a hoisting arm 2 for hoisting a jack is installed on the top of the vehicle frame 1, an arc-shaped support plate 3 is installed on one side of the vehicle frame 1, the axis of the arc-shaped support plate 3 is arranged horizontally, the opening of the arc-shaped support plate 3 is located above the arc-shaped support plate 3, and an arc-shaped pressing plate 4 is also rotatably arranged on one side of the arc-shaped support plate 3. When the arc-shaped pressing plate 4 rotates, one side of the arc-shaped pressing plate 4 has a degree of freedom to rotate towards the inside of the arc-shaped support plate 3. When this application is in use, the opening of the arc-shaped support plate 3 can be located above the arc-shaped support plate 3 by rotating the arc-shaped support plate 3. Thus, the jack can be placed inside the arc-shaped support plate 3 through the hoisting arm 2. And through the rotation of the arc-shaped support plate 3 and the arc-shaped pressing plate 4, the arc-shaped pressing plate 4 limits the jack inside the arc-shaped support plate 3 to prevent the jack from rolling and being damaged during the later movement of the trolley. And the operations of automatic clamping and loosening can be realized, avoiding the operation of manual fixation and facilitating the realization of automated operation in the later stage.

[0033] Specifically, in this embodiment, the hoisting arm 2 includes a vertical arm rotatably arranged on the vehicle frame 1. The axis of the rotation shaft of the vertical arm on the vehicle frame 1 is arranged vertically. A telescopic arm is also installed at the top of the vertical arm. The position of the telescopic arm on the vertical arm has a degree of freedom to adjust along the pitching angle. The telescopic arm can swing on the vertical arm through the drive of a hydraulic cylinder. At the same time, the telescopic arm includes a fixed arm hinged on the vertical arm and a sliding arm slidably arranged inside the fixed arm. The sliding arm is connected to the fixed arm through a hydraulic cylinder, so that the length of the telescopic arm can be adjusted. The vertical arm is installed on the vehicle frame 1 and is located on the side of the arc-shaped pressing plate 4 away from the arc-shaped support plate 3.

[0034] In some embodiments, the above-mentioned arc-shaped support plate 3 and arc-shaped pressing plate 4 can adopt structures such as Figure 1 , Figure 2 and Figure 3 as shown. Please refer toFigure 1 , Figure 2 and Figure 3 , the arc-shaped support plate 3 and the arc-shaped pressing plate 4 rotate in opposite directions. The arc-shaped support plate 3 and the arc-shaped pressing plate 4 are rotatably arranged on the vehicle frame 1. When a jack needs to be placed or taken, the arc-shaped support plate 3 and the arc-shaped pressing plate 4 can be driven to rotate so as to open the opening between the arc-shaped support plate 3 and the arc-shaped pressing plate 4. After the jack is placed inside the arc-shaped support plate 3, the opening of the arc-shaped support plate 3 can be rotated towards the direction of the arc-shaped pressing plate 4 by the rotation of the arc-shaped support plate 3. And the jack is limited inside the arc-shaped support plate 3 by the arc-shaped pressing plate 4. At the same time, the jack is pulled upwards by the lifting arm 2, and the jack can be limited by both the arc-shaped support plate 3 and the arc-shaped pressing plate 4, reducing the sway of the jack between the arc-shaped support plate 3 and the arc-shaped pressing plate 4.

[0035] In some embodiments, the above-mentioned driving assembly 5 can adopt the structure as shown in Figure 2 , Figure 3 . Referring to Figure 2 , Figure 3 together, the driving assembly 5 includes a first arc-shaped rack 51 and a first gear 52. The first arc-shaped rack 51 is fixedly installed on the outside of the arc-shaped support plate 3, and the first arc-shaped rack 51 is coaxially arranged with the arc-shaped support plate 3; the first gear 52 is rotatably arranged on the vehicle frame 1 and is meshed with the first arc-shaped rack 51. When the first gear 52 rotates, it can synchronously drive the first arc-shaped rack 51 to rotate. Specifically, two first arc-shaped racks 51 are installed on the outer side wall of the arc-shaped support plate 3, and the two first arc-shaped racks 51 are arranged in parallel at intervals along the axis of the arc-shaped support plate 3, and the two first gears 52 corresponding to the two first arc-shaped racks 51 are located below the arc-shaped support plate 3, which can play a certain supporting role for the arc-shaped support plate 3. And the two first gears 52 are coaxially arranged and share the same rotating shaft, and the two first gears 52 are both fixedly installed on the same rotating shaft.

[0036] In some embodiments, the above-mentioned vehicle frame 1 can adopt the structure as shown in Figure 3 . Referring to Figure 3 , a driving shaft 53 for driving the first gear 52 to rotate is also rotatably arranged on the vehicle frame 1, a first worm 54 is fixedly installed on the driving shaft 53, and a first worm gear 55 meshed with the first worm 54 is fixedly installed on the rotating shaft of the first gear 52. A driving shaft 53 is also rotatably arranged on the vehicle frame 1, and the driving shaft 53 is driven to rotate by a motor. A first worm 54 is fixedly installed on the driving shaft 53, the first worm 54 is coaxially arranged with the driving shaft 53, and a first worm gear 55 meshed with the first worm 54 is fixedly installed on the rotating shaft of the first gear 52, so that the first gear 52 can be driven to rotate by the driving shaft 53, and the position of the first gear 52 can be fixed by the self-locking characteristic of the worm and worm gear. The operation is convenient and the use is convenient.

[0037] In some embodiments, the above-mentioned vehicle frame 1 can adopt a structure as shown in Figure 2 、 Figure 3 . Referring to Figure 2 、 Figure 3 together, a guide plate 6 for installing the arc-shaped support plate 3 is fixedly installed on the vehicle frame 1. An arc-shaped groove for accommodating the end of the arc-shaped support plate 3 along the axial direction is arranged inside the guide plate 6. Elastic members 61 for pushing the arc-shaped support plate 3 to rotate are arranged at both ends of the arc-shaped groove. When the arc-shaped support plate 3 abuts against the elastic members 61, the first arc-shaped rack 51 disengages from the first gear 52. Two guide plates 6 for installing the arc-shaped support plate 3 are also installed on the vehicle frame 1. The guide plates 6 are located at both ends of the arc-shaped support plate 3 along the axial direction of the arc-shaped support plate 3, and both side edges of the arc-shaped support plate 3 are respectively located inside the arc-shaped grooves of the two guide plates 6. Through the arrangement of the guide plate 6, the stability of the arc-shaped support plate 3 during rotation can be improved. Elastic members 61 are installed at both ends of the arc-shaped groove, and the elastic members 61 are springs or elastic plates. The arc-shaped support plate 3 is slidably arranged inside the arc-shaped groove. When the arc-shaped support plate 3 rotates, the side edge of the arc-shaped support plate 3 can abut against the elastic members 61 and squeeze the elastic members 61 to deform. At the same time, the first gear 52 is located at the end of the first arc-shaped rack 51 and disengages from the first arc-shaped rack 51. Through the arrangement of the elastic members 61, the teeth on the first gear 52 can always contact the teeth on the first arc-shaped rack 51. When the first gear 52 rotates in the opposite direction, it can continue to drive the first arc-shaped rack 51 to rotate.

[0038] Specifically, in this embodiment, the first gear 52 can disengage from the first arc-shaped rack 51 during rotation, which can enable the first gear 52 to continuously rotate in the same direction. After the first gear 52 disengages from the first arc-shaped rack 51, the position of the first arc-shaped rack 51 will not change when the first gear 52 continues to rotate, which is convenient for fixing and switching the working position of the arc-shaped support plate 3.

[0039] In some embodiments, the above-mentioned vehicle frame 1 can adopt a structure as shown in Figure 1 、 Figure 2 and Figure 4 . Referring to Figure 1 、 Figure 2 and Figure 4, support arms 7 are also hingedly provided on both sides of the frame 1, and oil cylinders for supporting the support arms 7 on the ground are also installed at the ends of the support arms 7. A swing assembly 8 for synchronously driving the two support arms 7 to swing is also installed on the frame 1. Support arms 7 are hingedly provided on both sides of the frame 1, and the axis of the hinge shaft of the support arms 7 on the frame 1 is arranged along the vertical direction. Therefore, the support arms 7 can be unfolded according to the size of the on-site construction site during the operation. Oil cylinders are also installed at the ends of the support arms 7, which can be supported on the ground by the oil cylinders to achieve the fixation of the frame 1. At the same time, the support arms 7 are hingedly provided on the frame 1, and the unfolding angle of the support arms 7 can be freely adjusted according to the size of the on-site construction site.

[0040] Specifically, in this embodiment, support cylinders are installed on both sides of the support arm 7 provided on the frame 1, and the support cylinders on the frame 1 cooperate with the cylinders on the support arm 7 to lift the frame 1 to assist the operation.

[0041] In some embodiments, the swing assembly 8 may be configured as follows: Figure 4 See the structure shown. Figure 4 , the swing assembly 8 includes a second worm wheel 81 and a second worm 82. The second worm wheel 81 is fixedly mounted on the support arm 7 and is coaxially arranged with the hinge shaft of the support arm 7 on the frame 1; the second worm 82 is rotatably arranged on the frame 1 and is meshed with the second worm wheel, and the second worm 82 corresponding to the two support arms 7 are connected to each other by transmission. The second worm 82 is rotatably arranged on the frame 1, and the second worm wheel 81 is fixedly mounted on the support arm 7. The second worm wheel 81 is sleeved on the outer side of the hinge shaft of the support arm 7 on the frame 1. When the second worm 82 rotates, it can synchronously drive the second worm wheel 81 to rotate. Thereby, the swing of the support arm 7 is realized. And the two second worm wheels 82 corresponding to the two support arms 7 are connected to each other by transmission, so that the two support arms 7 can be synchronously unfolded or stored on the frame 1. And the support arm 7 can automatically fix the position of the support arm 7 through the self-locking characteristics of the worm wheel.

[0042] In some embodiments, the second worm 82 may be Figure 4 , Figure 5 See also Figure 4 , Figure 5, a driving rod 9 is also rotatably arranged on the vehicle frame 1. Two ends of the driving rod 9 are respectively in transmission connection with second worms 82 corresponding to two support arms 7. The driving rod 9 is also rotatably connected with a second gear 41. A second arc-shaped rack 42 meshing with the second gear 41 is fixedly installed on the outer side of the arc-shaped pressing plate 4. The axis of the driving rod 9 is perpendicular to the axis of the second worm 82. The rotating shaft on the second worm 82 is rotatably arranged on the vehicle frame 1, and the rotating shaft on the second worm 82 is in transmission connection with the driving rod 9 through bevel gears. The driving rod 9 is in transmission connection with the second gear 41 through spur gears. When the driving rod 9 rotates, it can drive the two support arms 7 to swing and at the same time drive the arc-shaped pressing plate 4 to rotate.

[0043] Specifically, in this embodiment, the installation method of the arc-shaped pressing plate 4 on the vehicle frame 1 is the same as that of the arc-shaped supporting plate 3 on the vehicle frame 1. Two guide plates 6 for installing the arc-shaped pressing plate 4 are also installed on the vehicle frame 1. Two ends of the arc-shaped pressing plate 4 are respectively slidably arranged inside the two guide plates 6, and elastic members 61 for abutting against the arc-shaped pressing plate 4 are arranged at two ends of the guide plates 6. When the second gear 41 rotates to the end of the second arc-shaped rack 42, it can continue to rotate and disengage from the second arc-shaped rack 42, so that after the arc-shaped pressing plate 4 moves in place, it will not affect the continuous swinging of the support arms 7 on both sides of the vehicle frame 1. It can not only realize that the arc-shaped pressing plate 4 and the support arm 7 adopt the same driving source. At the same time, it can avoid the movement stroke of the arc-shaped pressing plate 4 affecting the swinging stroke of the support arm 7.

[0044] Specifically, in this embodiment, during use, when the support arm 7 expands outwards, the working part of the arc-shaped pressing plate 4 rotates in a direction away from the inside of the arc-shaped supporting plate 3, so that when the support arm 7 expands, the jack can be lifted out of the inner wall of the arc-shaped supporting plate 3 through the lifting arm 2. When the support arm 7 is retracted onto the vehicle frame 1, the working part of the arc-shaped pressing plate 4 rotates towards the inside of the arc-shaped supporting plate 3, so as to realize the pressing of the jack, which is convenient for the later movement of the trolley.

[0045] In some embodiments, the above-mentioned driving rod 9 can adopt the structure as Figure 4 , Figure 5 shown. See Figure 4 , Figure 5, the driving rod 9 is in transmission connection with the first gear 52. The rotating shaft of the first gear 52 is rotatably arranged on the vehicle frame 1, and a third worm gear is fixedly installed on the rotating shaft of the first gear 52. A main shaft for driving the first gear 52 to rotate is also rotatably arranged on the vehicle frame 1, and a third worm meshing with the third worm gear is fixedly installed on the main shaft. A motor for driving the main shaft to rotate is fixedly installed on the vehicle frame 1. A vertical shaft is also rotatably arranged on the vehicle frame 1, and a fourth worm gear is fixedly installed on the vertical shaft. A fourth worm meshing with the fourth worm gear is fixedly installed on the driving rod 9. The vertical shaft and the main shaft are in transmission connection through a gearbox. Thus, the motor can drive the arc-shaped supporting plate 3 and the arc-shaped pressing plate 4 to rotate relative to each other simultaneously. At the same time, it can also drive the support arm 7 to swing synchronously.

[0046] Specifically, in this embodiment, when the support arm 7 is unfolded, the arc-shaped supporting plate 3 and the arc-shaped pressing plate 4 are unfolded in a relatively far-away direction from each other, increasing the opening size between the arc-shaped supporting plate 3 and the arc-shaped pressing plate 4, which is convenient for storing or taking out the jack. When the support arm 7 is retracted onto the vehicle frame 1, the arc-shaped supporting plate 3 and the arc-shaped pressing plate 4 move in a relatively close direction. Thus, when the support arm 7 is retracted onto the vehicle frame 1, the jack can be synchronously squeezed between the arc-shaped supporting plate 3 and the arc-shaped pressing plate 4. When the jack is clamped between the arc-shaped supporting plate 3 and the arc-shaped pressing plate 4, the first gear 52 disengages from the end of the first arc-shaped rack 51, and the second gear 41 disengages from the end of the second arc-shaped rack 42, thus not affecting the later retraction of the support arm 7.

[0047] In some embodiments, the above-mentioned arc-shaped supporting plate 3 can adopt structures such as Figure 2 , Figure 3 as shown. Referring to Figure 2 , Figure 3 together, a plurality of support rollers 31 for supporting the bottom of the arc-shaped supporting plate 3 are also rotatably arranged on the vehicle frame 1, and the support rollers 31 are rollingly arranged on the outer side surface of the arc-shaped supporting plate 3. A plurality of support rollers 31 are rotatably arranged on the vehicle frame 1, and the plurality of support rollers 31 are all rollingly arranged on the outer side surface of the arc-shaped supporting plate 3 and are located below the arc-shaped supporting plate 3. When the arc-shaped supporting plate 3 rotates, it can drive the support rollers 31 to rotate, thus playing a certain supporting role for the arc-shaped supporting plate 3.

[0048] Specifically, in this embodiment, when placing the jack on the arc-shaped supporting plate 3, the mouth of the arc-shaped supporting plate 3 faces upward, which is convenient for the jack to be placed into the arc-shaped groove of the arc-shaped supporting plate 3 through the hoisting of the hoisting arm 2. After the jack is placed on the arc-shaped supporting plate 3, when the arc-shaped supporting plate 3 rotates, it can drive the jack to rotate synchronously. The arc-shaped supporting plate 3 can limit the outward rolling of the jack, improving the stability of the jack's position.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
