Description

Technical Field

[0001] This utility model belongs to the field of concrete horizontal conveying technology, and relates to a transfer belt conveyor for a concrete horizontal belt conveyor system used in T-beam production. Background Technology

[0002] In the prefabrication of highway bridges, the main method for concrete transportation and pouring is the concrete mixer truck + hopper method. This method suffers from long pouring times, significant concrete slump loss, and overlapping operations involving concrete pouring, rebar hoisting, and formwork installation. In recent years, to address these issues, China has introduced a concrete conveying technology using torpedo-shaped concrete mixers and placing booms, which is being widely promoted in smart beam yards. The torpedo-shaped concrete mixer uses a circular track, positioned above the mixing plant and the concrete pouring area. The circular track has a turning radius of 6 meters. Four torpedo-shaped concrete mixers are installed on the track, transporting concrete from the mixing plant to the placing boom along the circular track. Each mixer has a volume of 3 cubic meters. The mixers are operated remotely with multi-function buttons, allowing for multi-point dispensing to accommodate various production conditions. The travel speed is adjustable from 0-60 m / min. Dispensing is done by a 180° rotation, aided by a vibrating motor. The torpedo-shaped concrete mixer travels at 55 m / min on a straight line and 20 m / min on a curved path. The circular track has a straight section of 162m (long side) and a short section of 20m (short side), with a curve length of 18.84m. The time for one loop is 7.56 minutes. The unloading time is 6 minutes. Each trip transports 3 cubic meters of material, resulting in a final efficiency of 2.63 minutes / m². 3 The inventors discovered through on-site investigation that torpedo canisters suffered from a series of defects, including high failure rates, slow operating speeds, and difficulties in cleaning; the use of horizontal conveyor belts for concrete transport solved these problems.

[0003] However, for placing booms with multiple T-beam molds, fixed horizontal conveyor belts cannot meet the requirements of high production efficiency. If each placing boom is equipped with a fixed conveyor belt, the cost is high and the utilization rate is low. Utility Model Content

[0015] The beneficial effects of this utility model are as follows: Compared with the prior art, the effects of this utility model are as follows:

[0016] (1) This utility model adopts a walking concrete conveyor belt, which can realize the covering and transfer of multiple placing machines at one end of the horizontal conveyor belt unloading. It can greatly improve production efficiency, increase equipment utilization, and reduce production costs. Moreover, it adopts multiple rows of walking wheels, making walking stable and reliable. It is equipped with unloading hopper and unloading scraper, which can unload at fixed points and keep the belt unloading clean. It adopts a dual power mechanism drive, which can serve as a backup on the one hand, and on the other hand, can improve power and make walking more efficient and stable when dealing with long transfer belts.

[0017] (2) The unloading scraper adopts a double-layer scraper plate, which can play a better role in scraping mud. The hard plastic scraper plate provides better support rigidity.

[0020] (5) The arrangement of the slope surface facilitates the automatic collection and outflow of accumulated mud, and the vibration generated during the belt movement will also help the mud slide off.

[0021] (6) The combination of T-strips and T-slots makes installation convenient and quick, and the connection is reliable and stable after installation;

[0022] (7) When the touch switch is touched, the brake shoe positioning device will position one row of walking wheels in the direction of travel according to the touch signal. After positioning, another machine will be used to position the other row of walking wheels. After the two rows of walking wheels are positioned, the walking belt is limited to avoid the transfer belt from moving too much and failing to accurately dock with the cloth bucket. It also avoids movement during the unloading process, realizes fixed-point delivery and unloading into the cloth machine, and improves the reliability of unloading.

[0023] (8) By driving the iron chip block to move upward, the traveling wheel can be limited; after the iron shoe block moves downward, it is lower than the top rail surface of the traveling track.

[0024] (9) The use of double guide pins can make qualitative movement of the iron filings, improve the accuracy of qualitative movement, and also achieve the function of preventing detachment;

[0025] (10) After the hydraulic cylinder extends, it can move the iron chip block down by the connecting rod. After it retracts, it can move the iron shoe block up.

[0032] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1: As Figure 1-6 As shown, the transfer belt conveyor of the concrete horizontal belt conveyor system used for T-beam production includes a conveyor belt 1, which is mounted on a belt conveyor frame 2. The bottom of the belt conveyor frame 2 is provided with multiple rows of traveling wheels 3. The two ends of the conveyor belt 1 are respectively provided with a first unloading hopper 4 and a second unloading hopper 5. Unloading scrapers 10 are installed in the first unloading hopper 4 and the second unloading hopper 5. The first row of traveling wheels 3 and the last row of traveling wheels 3 are respectively equipped with a first power drive mechanism 6 and a second power mechanism 7, which are mounted on a traveling track 13. The traveling track 13 is mounted on a frame 8, and the frame 8 is connected to the ground through a column 9.

[0034] To achieve better scraping results on the concrete surface indicated by the belt, such as Figure 2-3As shown, the concrete horizontal belt conveyor system also includes an upper belt discharge scraper 10. The discharge scraper 10 includes a first scraper plate 1001 and a second scraper plate 1002. The first scraper plate 1001 and the second scraper plate 1002 are made of rigid plastic plates and are fixedly connected to both sides of an inverted T-shaped metal support plate 1003 with a gap. Flexible rubber scraper blades 1004 are arranged along the length of the top of the first scraper plate 1001 and the second scraper plate 1002. 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 4 near the middle and their ends extend out of the rear end of the side wall of the discharge hopper 4 and are fixedly connected. The drive shaft 1008 is hinged in the middle 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 4, and this hinge point is located below the hinge point between the swing rod 1005 and the side wall. After the cylinder 1007 extends, it can simultaneously press the first layer scraper 1001 and the second layer scraper 1002 against the lower left of the discharge end of the upper belt conveyor. The use of double-layer scraper plates can better scrape off the mud. The hard plastic scraper plates provide better support rigidity, and when the flexible plastic scraper blades contact the belt, they can more stably scrape off the concrete adhering to the belt, ensuring stable and reliable scraping. On the other hand, they also provide better shock absorption. To prevent excessive vibration from degrading the scraping effect, a T-shaped metal support plate is used. This provides spacing and facilitates installation. Corrosion-resistant bolts (110) pass through the two scraper blades and the T-shaped metal support plate, and are then secured with corrosion-resistant nuts. The two scraper blades and the T-shaped metal support plate are also positioned using locating pins (1011). The scraper blades have stepped holes for receiving the bolt heads and nuts. Sealing the stepped holes with a cap prevents cement mortar from entering and corroding the bolts. A cylinder controls the extension and retraction of the scraper blades during use or cleaning. This contact allows water to enter and clean the scraper blades. The cylinder has a washing and rinsing function with the scraper blade. On the other hand, the cylinder extension and retraction can maintain a certain elasticity and avoid poor stability of the scraper blade contact due to the fixing method. A dust cover 1009 is installed above the cylinder to block the cement mortar from falling and protect the cylinder. The top surface of the metal support plate 1003 is provided with symmetrical slopes on both sides, which facilitates the automatic collection and flowout of accumulated mud. The vibration generated during the belt movement also helps the mud slide off. The flexible rubber scraper blade 1004 has a cylindrical structure and a T-shaped strip 1012 is provided at the bottom. The T-shaped strip 1012 is elastically squeezed and inserted into the T-shaped groove at the top of the first scraper blade 1001 or the second scraper blade 1002, which is convenient and quick to install.

[0035] like Figure 4-5As shown, to achieve stable unloading of material from the lower conveyor belt into the fabric placing machine, the transfer conveyor includes a brake shoe positioning device 11 and a touch switch 12. Two brake shoe positioning devices 11 are installed on the conveyor frame 5 to lock the front and rear rows of traveling wheels 14. The touch switch 12 is installed on one side of the traveling track 13. When the touch switch is activated, the brake shoe positioning device 11 positions one row of traveling wheels in the traveling direction based on the touch signal. After positioning, another device positions the other row of traveling wheels. Positioning both rows of traveling wheels limits the movement of the conveyor belt, preventing excessive movement that could prevent precise docking with the fabric hopper and also preventing movement during material unloading. The material is conveyed to the placing boom at a fixed point to improve unloading reliability. The brake shoe positioning device 11 includes a shoe block 1101 and a lifting and lowering drive mechanism 1102. The shoe block 1101 is vertically slidably connected in a sliding groove 1103. After moving upward, the arc-shaped surface of the shoe block can fit against the surface of the traveling wheel. The bottom is connected to the lifting and lowering drive mechanism 1102. By driving the shoe block to move upward, the traveling wheel can be limited. After the shoe block moves downward, it is lower than the top rail surface of the traveling track. The shoe block 1101 is provided with a vertical strip hole 1104. Two guide pins 1105 are vertically spaced in the vertical strip hole 1104 and fixedly connected to the two guide pins 1105, which are fixedly connected to the fixed frame 1106. The fixed frame 1106 is fixedly connected to the notch of the traveling track 13. It uses double guide pins to allow for qualitative movement of the iron filings, improving the accuracy of the qualitative movement and preventing detachment. The up-and-down lifting drive mechanism 1102 includes a pressure rod 1107, a first connecting rod 1108, a second connecting rod 1109, and a drive hydraulic cylinder 1110. One end of the pressure rod 1107 abuts against the bottom of the iron shoe block 1101 and is hinged to the bottom of the traveling track 13 near the center via a hinge seat 1111. The other end of the pressure rod 1107 is hinged to the first connecting rod 1108, and the other end of the first connecting rod 1108 is hinged to the cylinder rod end of the drive hydraulic cylinder 1110. One end of the second connecting rod 1109 is hinged to the upper middle part of the first connecting rod 1108, and the other end is hinged... The cylinder seat of the driving hydraulic cylinder 1110 is connected to the top of the cylinder seat near the cylinder rod end. The tail of the cylinder seat of the driving hydraulic cylinder 1110 is hinged to the vertical cantilever seat 1112. The upper end of the vertical cantilever seat 1112 is fixedly connected to the bottom of the walking track 13. After the driving hydraulic cylinder extends, it can move the iron chip block down by the connecting rod. After it retracts, it can move the iron shoe block up. The power mechanism is arranged away from the iron chip block for easy installation. The connecting rod mechanism realizes power transmission, and the force transmission is stable and reliable. It can realize slow application of force and reduce impact. The pressure rod 1107 is set in the shape of a spoon or is rotatably connected to a roller at the bottom end of the iron shoe block 1101. When it is spoon-shaped, the convex surface is in contact with the bottom surface of the iron shoe block 1101, which can reduce friction and improve pressing stability.
