Description

Technical Field

[0002] During the prefabrication of highway bridges, the main method of concrete transportation and pouring is the pouring method of tank truck + hopper. In the transportation of concrete tank trucks and the entry of buckets into the mold, there are long pouring times, large concrete slump losses, and cross-operation of concrete pouring, steel bar lifting, and formwork installation. In recent years, in order to solve such problems, the domestic torpedo tank + concrete placing machine concrete transportation process has been introduced and vigorously promoted in domestic smart beam yards. The torpedo tank track adopts a circular track, which is set from the mixing station to the top of the concrete pouring area. The turning radius of the circular track is 6m. Four torpedo tanks are installed on the track, and the torpedo tanks complete the transportation task of concrete from the mixing station to the concrete placing machine along the circular track. The volume of the torpedo tank is 3m3. The torpedo tank is equipped with a remote control and is equipped with a multi-function button. It can discharge materials at multiple points to meet multiple conditions in the production process. The travel speed is adjustable from 0 to 60m / min. The material is dropped by flipping 180°, and a vibration motor is equipped to cooperate with the drop; the torpedo tank travels at a straight line speed of 55m / min and a curve speed of 20m / min. The circular track has a straight line length of 162m (long side), a short side length of 20m (short side), and a curve length of 18.84m. The single-circuit running time is 7.56min. The material receiving time of the unloader is 6min. Each time the material is transported 3 cubic meters, the final efficiency is 2.63min / m 3 The inventor found through on-site investigation that the torpedo tank had a series of defects such as high failure rate, slow running speed and difficult cleaning; the use of a horizontal conveyor belt to transport concrete can solve this problem.

Due to the sufficient width, it ensures that after quickly absorbing water at the bottom, it gradually enters the sponge part with less water absorption at the top, so as to better remove moisture from the belt surface, at least in one The belt is cleaned within a cycle, which can complete the cleaning of most of the water absorbed by the belt, and improve the drying efficiency through natural drying. The water inlet is arranged as a row of nozzles 923, and a row of nozzles 923 are connected in parallel to the main pipe 924. The main pipe 924 is connected to the water inlet pipe. The main pipe 924 is fixedly connected to the inner side of the cleaning box near the top through a clamp and ensures that the nozzles are arranged in a downward direction, and the water flow is tilted to spray on the output belt section that is not immersed in water. For the belt after brushing, secondary flushing is achieved, and the cleaning is more thorough. The clamp connection is convenient for angle adjustment to find the best flushing angle. The water inlet pipe is connected to the water pump to ensure stable water pressure.

[0032] In order to achieve better scraping effect of concrete on the belt surface, such as Figure 12-13As shown, the concrete horizontal belt conveyor system also includes a discharge scraper 10 of the upper belt, and the discharge scraper 10 includes a first-layer scraper plate 1001 and a second-layer scraper plate 1002. The first-layer scraper plate 1001 and the second-layer scraper plate 1002 are hard plastic plates, which are fixedly connected to both sides of an inverted T-shaped metal support plate 1003 to maintain a gap arrangement. Flexible rubber scraper blades 1004 are arranged on the top of the first-layer scraper plate 1001 and the second-layer scraper plate 1002 along their length direction. The metal support plate 1003 is fixedly connected to two swing rods 1005 near both ends. The two swing rods 1005 are hinged to the side wall of the discharge hopper 1006 near the middle and the two ends extend out of the rear end of the side wall of the discharge hopper 1006. The drive shaft 1008 is fixedly connected, and the middle part of the drive shaft 1008 is hinged to the cylinder rod of the cylinder 1007. The cylinder seat of the cylinder 1007 is hinged to the side wall of the discharge hopper 1006 and the hinge is located below the hinge of the swing rod 1005 and the side wall. After the cylinder 1007 is extended, the first scraper plate 1001 and the second scraper plate 1002 can be simultaneously pressed against the lower left side of the discharge end of the upper belt conveyor. The double-layer scraper plate can play a better role in scraping away the mud. The hard plastic scraper plate, on the one hand, has better supporting rigidity. When the flexible plastic scraper blade contacts the belt, it can more stably scrape away the concrete attached to the belt, and the scraping is stable and reliable. On the other hand, it plays a better role in reducing In order to improve the vibration effect and avoid the deterioration of the scraping effect due to excessive vibration, a T-shaped metal support plate is used, which provides a gap arrangement on the one hand and is convenient for installation on the other hand. After the corrosion-resistant bolts 110 pass through the two scraper plates and the T-shaped metal support plate, they are locked and fixed with corrosion-resistant nuts. The two scraper plates and the T-shaped metal support plate are also positioned with positioning pins 1011. The scraper plates are provided with step holes for accommodating the big heads of the bolts and the nuts. The step holes are sealed with a sealing cover to prevent cement mortar from entering the step holes and corroding the bolts. A cylinder is used for telescopic control and abutment. The scraper plates are contacted during use or cleaning. On the one hand, if water enters after the scraper plates are in contact, the end of the scraper plates can be On the other hand, the cylinder can be extended and retracted to maintain a certain elastic effect, avoiding the poor stability of the scraper plate contact caused by the fixing method. A dust cover 1009 is installed above the cylinder to block the falling cement mortar and protect the cylinder. The top surface of the metal support plate 1003 is provided with symmetrical slopes on both sides, which is convenient for the accumulated mud to automatically converge and flow out, and the vibration generated during the movement of the belt will also help the mud to slide off. The flexible rubber scraper blade 1004 is a cylindrical structure with a T-bar 1012 at the bottom. The T-bar 1012 is elastically squeezed and stuck in the T-slot on the top of the first scraper plate 1001 or the second scraper plate 1002, which is easy and quick to install.

[0033] like Figure 14-15As shown, in order to realize stable unloading of the lower belt into the concrete placing machine, the concrete horizontal belt conveyor system also includes a lower walking belt positioning device, which includes a brake shoe positioning device 11 and a touch switch 12. The brake shoe positioning device 1 adopts two and is installed on the belt conveyor frame 5. It can lock the front and rear rows of walking wheels 14. The touch switch 12 is installed on one side of the walking track 13. When the touch switch is touched, the brake shoe positioning device 11 is controlled according to the touch signal to position a row of walking wheels in the walking direction. After positioning, another row of walking wheels is positioned. After the two rows of walking wheels are positioned, the walking belt is limited to avoid displacement during the discharge process. The brake shoe positioning device 11 comprises an iron shoe block 1101 and an up-and-down lifting drive mechanism 1102. The iron shoe block 1101 is vertically slidably connected in the sliding groove 1103. After moving up, the arc surface of the iron shoe block can fit on the wheel surface of the walking wheel. The bottom is connected with an up-and-down lifting drive mechanism 1102. After driving the iron chip block to move up, the walking wheel can be limited. After the iron shoe block moves down, it is lower than the top rail surface of the walking guide rail. The iron shoe block 1101 is provided with a vertical strip hole 1104. The vertical strip hole 1104 is vertically spaced with two guide pins 1105 and fixedly connected to the two guide pins 1105. The fixed frame 1106 is fixedly connected to the two guide pins 1105. On the upper part, the fixed frame 1106 is fixedly connected to the notch of the walking guide rail 13, and the double guide pins are adopted to perform qualitative movement of the iron chip block, improve the accuracy of qualitative movement, and realize the anti-slip effect; the up and down lifting drive mechanism 1102 includes a pressure rod 1107, a connecting rod 1108, a connecting rod 2 1109 and a driving hydraulic cylinder 1110, one end of the pressure rod 1107 is against the bottom of the iron shoe block 1101, and is hinged to the bottom of the walking guide rail 13 near the middle through a hinge seat 1111, the other end of the pressure rod 1107 is hinged on the connecting rod 1 1108, and the other end of the connecting rod 1 1108 is hinged to the cylinder rod end of the driving hydraulic cylinder 1110, one end of the connecting rod 2 1109 is hinged to the middle and upper part of the connecting rod 1 1108, and the other end of the connecting rod 1109 is hinged to the cylinder rod end of the driving hydraulic cylinder 1110. The end is hinged at the top of the cylinder seat of the driving hydraulic cylinder 1110 near one end of the cylinder rod, and the tail of the cylinder seat of the driving hydraulic cylinder 1110 is hinged on the vertical cantilever seat 1112. The upper end of the vertical cantilever seat 1112 is fixedly connected to the bottom of the walking guide rail 13. After the driving hydraulic cylinder is extended, the connecting rod can move the iron filing block downward. After retracting, the iron shoe block can be moved upward. The power mechanism is arranged away from the iron filing block, which is convenient for installation. The connecting rod mechanism realizes power transmission, and the force transmission is stable and reliable. It can achieve slow force application and reduce impact; the pressure rod 1107 is in contact with the bottom end of the iron shoe block 1101 and is set in a spoon shape or rotatably connected to a roller. When it is in a spoon shape, the convex surface is against the bottom surface of the iron shoe block 1101, which can reduce friction and improve pressing stability. The concrete horizontal belt conveyor is used to transport concrete, which reduces the original torpedo tank concrete transportation time from 2.63min / m 3Reduced to 0.653min / m 3 , which improves the transportation efficiency of concrete by 300% and also reduces the loss of slump during concrete transportation.

[0034] The torpedo tank is a concentrated load on the track, which requires a higher track strength and a higher track cost. The concrete horizontal belt conveyor adopts surface load bearing, which has low requirements for belt bracket stiffness and bearing capacity, and has the advantage of cost saving.

[0035] There are 4 torpedo tanks on the circular track. If one of the torpedo tanks fails, the entire concrete transportation system cannot be used, which has a great impact on production. The cleaning of torpedo tanks is complicated. After each use, they need to be cleaned one by one, which takes a long time. By installing a customized scraper on the belt conveyor, the belt conveyor is exempted from cleaning, which reduces the waste of water resources and sewage treatment caused by the cleaning of transportation equipment.

[0036] In terms of cost, the torpedo tank and running track of Guangmian Smart Beam Yard cost 2.72 million yuan, and the belt conveyor cost 2.2 million yuan, saving 520,000 yuan.

[0038] The upper short belt conveyor (length 65m) + lower short belt conveyor (length 23m) are responsible for the transportation and pouring of concrete from the nearby No. 1-3 concrete placing machines.

[0039] The upper long belt conveyor (length 120m) + lower long belt conveyor (length 36m) are responsible for the transportation and pouring of concrete from the No. 4-6 concrete placing cranes in the distance.

[0040] The upper short belt conveyor and the upper long belt conveyor rotate forward to complete the concrete transportation from the mixing station to the lower belt.

[0041] The lower short belt conveyor completes the concrete transportation from the upper belt to the No. 1, 2 and 3 concrete placing booms by forward and reverse rotation.
