Description

Technical Field

[0001] This utility model relates to the field of fabric spreading table technology, and in particular to a multifunctional mobile fabric spreading table. Background Technology

[0002] In the production process of prestressed concrete slabs and precast floor slabs, concrete placing equipment is typically used to place the concrete slurry. Traditional placing equipment is mostly fixed in structure and its position is difficult to adjust flexibly. When facing the production needs of precast slabs of different sizes and layouts, it is usually necessary to use dedicated machines. For small processing workshops, purchasing a large number of machines is not practical and it is also impossible to control production costs.

[0003] For example, a wide-mouth concrete distributor, material distributor and production system for precast concrete components disclosed in patent application number CN202020279778.1 mainly includes a hopper, a material dispensing nozzle and a controller. The material dispensing nozzle is composed of a bottom plate and part of a side plate. The part without the side plate is the discharge port. The material dispensing nozzle is connected to the lower part of the hopper. The controller is installed on the material dispensing nozzle and / or on the hopper. The concrete in the hopper accumulates on the material dispensing nozzle. When the controller is working, the concrete in the hopper is discharged from the discharge port for material distribution.

[0004] It can be seen that when the above-mentioned concrete placing device is used to produce concrete slurry for prestressed concrete slabs and precast floor slabs, its relatively fixed and simple structure during the placing process cannot meet the different requirements of different thicknesses; at the same time, the scraping effect on the surface of the slurry after placing is poor, and the smoothness of the slurry surface after placing cannot be guaranteed.

[0005] Therefore, it is necessary to design a material feeding platform structure that can handle the production of prestressed concrete slabs and precast floor slabs of various sizes in practical production applications. Utility Model Content

[0030] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-4 As shown in the image.

[0031] Example 1: A multifunctional mobile concrete distribution platform includes a receiving platform 1. A support and guiding mechanism is provided above the receiving platform 1. Horizontal rails 2 are fixedly installed on the ground below both ends of the support and guiding mechanism. Support sliding members are slidably engaged on each of the horizontal rails 2. The top of each support sliding member is fixed to the bottom of the support and guiding mechanism. The rear end of each support sliding member is connected to an external telescopic device. A concrete distribution unit is installed on the support and guiding mechanism. The bottom of the concrete distribution unit extends above the receiving platform 1 and is used to distribute concrete onto the top of the receiving platform 1. The top of the concrete distribution unit is used to connect to an external feeding device, which supplies concrete slurry into it. An adjustable scraping mechanism is installed at the bottom of the concrete distribution unit.

[0032] When the multi-functional mobile fabric table is in operation, under the action of the external telescopic device, it can drive the supporting sliding parts at both ends to move back and forth along the length direction of the two transverse tracks 2 to achieve transverse adjustment, thereby meeting the needs of different fabric widths in the transverse direction.

[0033] When the concrete placement unit is laying concrete longitudinally, the unit itself can move along the length of the support and guide mechanism as needed. During the movement, the moving speed and the speed of concrete slurry output are controlled to control the amount of concrete laid.

[0034] After the concrete is laid, the adjustable scraping mechanism can quickly smooth and scrape the concrete slurry laid on the top of the receiving platform 1, ensuring the flatness of the concrete after laying.

[0035] The external telescopic device pushes the support sliding component to slide on the transverse track 2, enabling the support guiding mechanism and the cloth-laying unit to move laterally; the cloth-laying unit itself moves longitudinally on the support guiding mechanism, while controlling the moving speed and the slurry output speed to control the amount of cloth laid; the adjustable scraping mechanism smooths the slurry after the cloth is laid.

[0036] The entire material spreading platform allows for flexible material spreading in both horizontal and vertical directions, meeting the needs of different construction scenarios for material width and quantity; the scraping mechanism ensures the flatness of the material and improves construction quality.

[0037] Based on any of the above technical solutions, a further optimization is made as follows: the fabric unit includes a horizontally arranged rigid frame 3, the supporting sliding members are fixedly installed at the bottom of both ends of the rigid frame 3, and two horizontal rails 4 are fixedly installed at the top of the two horizontal sections of the rigid frame 3, which are arranged horizontally along their left and right length directions. The fabric unit is installed in the space between the two horizontal rails 4, and the fabric unit can reciprocate along the length direction of the two horizontal rails 4 when it is working.

[0038] The rigid frame 3 achieves lateral movement through the cooperation of the supporting sliding components and the transverse track 2. The horizontal track 4 on the rigid frame 3 provides a longitudinal movement track for other components within the fabric placement unit, while also providing a stable support structure for the fabric placement unit, ensuring its stability during lateral and longitudinal movement and improving fabric placement accuracy. Compared to traditional simple support methods, it is more adaptable to complex construction conditions.

[0039] Based on any of the above technical solutions, a further optimization is made as follows: The fabric placement unit includes a translation frame 5 disposed above the two horizontal rails 4. At the bottom of each end of the translation frame 5, rail wheels 6 are respectively installed and engaged with the corresponding horizontal rails 4 below them. The two rail wheels 6 located at the same end are connected by an axle 7. The outer end of the axle 7 on the right side extends movably to the outer end face of the translation frame 5 and is connected to a drive motor 8 fixed on its surface. The drive motor 8 rotates to drive each rail wheel 6 to move horizontally as needed. A fabric placement machine 9 is fixedly installed in the central space of the translation frame 5. A hopper 10 for cooperating with external feeding equipment is provided on the top of the fabric placement machine 9, and a discharge port 11 is provided on one side of the lower part of the fabric placement machine 9. The fabric placement machine 9 can be any existing fabric placement machine, and will not be described in detail further.

[0040] The drive motor 8 rotates, driving the right axle 7, which in turn causes the track wheel 6 to roll on the horizontal track 4, realizing the longitudinal movement of the translation frame 5 and the concrete placing boom 9. An external feeding device supplies material to the concrete placing boom 9 through the hopper 10, and the concrete placing boom 9 discharges material through the discharge port 11. This achieves automatic longitudinal movement of the concrete placing unit, facilitating precise control of the placing position and providing a stable installation platform for the concrete placing boom 9, ensuring smooth concrete placing operations. The combination of the drive motor 8 and the track wheel 6 enables automatic longitudinal movement, significantly improving the automation level and construction efficiency of concrete placing compared to the traditional manual pushing method, while reducing labor costs.

[0041] Based on any of the above technical solutions, a further optimization is made as follows: the adjustable scraping mechanism includes a scraper plate 12 fixedly installed below the fabric placing machine 9. The right end of the scraper plate 12 is movably hinged to a right ear seat 13 fixedly connected to the bottom of the fabric placing machine 9. The right end of the scraper plate 12 is inclined upward. A left ear seat 14 is fixed to the bottom of the fabric placing machine 9 on one side of the right ear seat 13. A control electric cylinder 15 is provided between the left ear seat 14 and the scraper plate 12. The upper end of the cylinder of the control electric cylinder 15 is movably hinged to the left ear seat 14. The lower end of the telescopic end of the control electric cylinder 15 is movably hinged to the upper part of the scraper plate 12. The control electric cylinder 15 controls the tilt angle of the left end of the scraper plate 12 by telescopic control.

[0042] By controlling the extension and retraction of the electric cylinder 15, the scraper 12 is rotated around the right ear seat 13, changing the tilt angle of the left end of the scraper 12, thereby adjusting the scraping height and force. During operation, the angle of the scraper 12 can be flexibly adjusted according to the actual material placement situation to improve the scraping effect and ensure a smooth surface of the material; it also performs a leveling treatment on the concrete slurry after material placement to ensure the quality of the material placement.

[0043] By precisely adjusting the angle of the scraper plate 12 by controlling the electric cylinder 15, compared with the traditional fixed-angle scraper device, it can better adapt to fabrics with different thicknesses and surface requirements, thus improving the adaptability and practicality of the equipment.

[0044] Example 2: Compared with Example 1, this example also includes the following technical features:

[0045] Based on any of the above technical solutions, a further optimization is made by installing a front cleaning unit on the right side wall of the fabric placing machine 9 and a rear pneumatic unit on the left side wall of the fabric placing machine 9.

[0046] The front cleaning unit and the rear pneumatic unit designed in this utility model are respectively installed on the two side walls of the fabric placing machine 9, and play their respective auxiliary roles in the fabric placing operation.

[0047] The pre-cleaning unit cleans the receiving platform 1 before the material is placed, reducing the impact of impurities on the material. The rear pneumatic unit removes dust and cools the drive components of the placing boom 9, extending the service life of the equipment. At the same time, it provides auxiliary treatment for the concrete slurry after the material is placed, enabling it to have the functions of cleaning the receiving platform 1, protecting the drive components of the placing boom 9, and assisting in the treatment of the concrete slurry after the material is placed.

[0048] Based on any of the above technical solutions, a further optimization is made as follows: the pre-cleaning unit includes a right mounting base 16 that is horizontally set and fixedly installed on the right side wall of the fabric distribution machine 9. A first motor 17 is installed at the bottom of the right mounting base 16. A first high-pressure air nozzle 18 is fixedly installed at the bottom of the motor shaft of the first motor 17. The jet end of the first high-pressure air nozzle 18 is inclined downward and faces the surface of the receiving platform 1. The first high-pressure air nozzle 18 is connected to an external air pump device.

[0049] During operation, the first motor 17 drives the first high-pressure air nozzle 18 to rotate, and an external air pump provides high-pressure gas. The high-pressure gas is sprayed out from the first high-pressure air nozzle 18 to clean the surface of the receiving platform 1. This effectively removes dust and impurities from the surface of the receiving platform 1, preventing them from mixing into the concrete slurry and ensuring the quality of the fabric placement. It achieves the cleaning function of the receiving platform 1, providing a clean working surface for the fabric placement operation. Here, using a rotating high-pressure air nozzle to clean the receiving platform 1 offers better cleaning results and higher efficiency compared to traditional manual cleaning methods, and it can be performed simultaneously with the fabric placement operation, saving time.

[0050] Based on any of the above technical solutions, a further optimization is made as follows: the rear pneumatic unit includes a left mounting base 19 that is horizontally set and fixedly installed on the left side wall of the concrete placing machine 9. A second motor 20 is installed at the bottom of the left mounting base 19. A second air nozzle 21 is fixedly installed at the bottom of the motor shaft of the second motor 20. The second air nozzle 21 is provided with two air jet outlets, one of which is horizontally set towards the drive component of the concrete placing machine 9 and is used for dust removal and cooling, and the other is inclined downward and set towards the concrete slurry after the concrete is spread on the receiving platform 1.

[0051] During operation, the second motor 20 drives the second air nozzle 21 to rotate, and an external air pump supplies gas. The two air outlets respectively perform dust removal and cooling on the drive components of the placing boom 9 and provide auxiliary treatment for the concrete slurry after placement. This protects the drive components of the placing boom 9 and extends the service life of the equipment; at the same time, it provides auxiliary treatment for the concrete slurry after placement, improving the surface condition of the slurry; thus achieving the functions of dust removal and cooling on the drive components of the placing boom 9 and auxiliary treatment for the concrete slurry after placement.

[0052] By using a single air nozzle, the device can perform two functions: protecting the drive components and assisting in the treatment of concrete slurry. This simplifies the equipment structure and improves its integration and functionality.

[0053] Based on any of the above technical solutions, a further optimization is made as follows: a position switch 22 is installed on the end face of both the left and right ends of the translation frame 5, and a limit plate seat 23 is fixedly installed at the bottom of both the left and right ends of the rigid frame 3, and each of the limit plate seats 23 is used to cooperate with the position switch 22 at the corresponding position.

[0054] When the translation frame 5 moves to the set position, the position switch 22 contacts the limit plate seat 23, triggering a signal to control the translation frame 5 to stop moving; thereby precisely controlling the movement position of the translation frame 5, preventing it from exceeding the safe range, ensuring the safe operation of the equipment, and realizing precise control of the longitudinal movement position of the fabric unit.

[0055] Based on any of the above technical solutions, a further optimization is made as follows: the supporting sliding component includes two vertical I-beams 24 spaced apart along the length direction of the transverse track 2 and arranged vertically. The tops of the two vertical I-beams 24 are fixed to the bottom of the rigid frame 3. A slide block 25 is fixedly installed at the bottom of each vertical I-beam 24. The bottom of each slide block 25 is slidably engaged with the top of the transverse track 2 at the corresponding position.

[0056] The support and sliding component, consisting of the vertical I-beam 24 and the slide block 25, slides on the transverse track 2 via the slide block 25, thereby enabling the lateral movement of the rigid frame 3 and the fabric unit. This provides stable lateral movement support for the fabric unit and ensures the smoothness of the lateral movement process.

[0057] Specific work process:

[0058] Preparation phase: Place the multi-functional mobile concrete placement platform on the construction site and connect the external material supply equipment to the top of the concrete placement unit to ensure a stable supply of concrete slurry.

[0059] At the same time, the external air pump equipment is connected to the front cleaning unit and the rear pneumatic unit respectively to provide power for subsequent cleaning, dust removal and cooling work.

[0060] Material receiving platform cleaning: Before the concrete placement operation begins, the pre-cleaning unit is activated. The first motor 17, installed at the bottom of the right mounting base 16 on the right side wall of the concrete placing machine 9, rotates, driving the first high-pressure air nozzle 18 at the bottom of the motor shaft to rotate. High-pressure gas delivered by an external air pump is sprayed out from the jet end and acts obliquely downwards on the surface of the material receiving platform 1, effectively removing dust and impurities from the platform, preventing these foreign objects from mixing into the concrete slurry, and ensuring the quality of the concrete placement.

[0061] Lateral fabric placement adjustment: Activate the external telescopic device according to construction needs. The telescopic device pushes the support sliding component. Since the support sliding component is slidably engaged with the lateral track 2, and the top of the support sliding component is fixed to the bottom of the support guide mechanism, the support sliding component will move horizontally along the length of the lateral track 2, causing the support guide mechanism and the fabric unit to move laterally, thereby adjusting the fabric width to meet the lateral fabric placement requirements of different construction areas.

[0062] Longitudinal Concrete Placement and Quantity Control: When the concrete placement unit is ready for longitudinal placement, the drive motor 8 is started. The drive motor 8, mounted on the right side of the translation frame 5, rotates, driving the right axle 7, which in turn causes the track wheel 6, which engages with the horizontal track 4, to roll. The translation frame 5 moves along the horizontal track 4, and the concrete placement machine 9, mounted in the middle of the translation frame 5, moves accordingly. During the movement, the speed of the translation frame 5 is adjusted by controlling the rotation speed of the drive motor 8, while simultaneously controlling the speed at which the concrete placement machine 9 outputs concrete slurry, thereby precisely controlling the quantity of concrete placed and achieving uniform placement.

[0063] Post-layout processing: After laying, the adjustable scraping mechanism is activated. The electric cylinder 15 is extended and retracted. The upper end of the cylinder is hinged to the left ear seat 14 at the bottom of the placing boom 9, and the lower end of the extension end is hinged to the upper part of the scraper plate 12. By extending and retracting, the tilt angle of the left end of the scraper plate 12 is changed, smoothing and scraping the concrete slurry laid on top of the receiving platform 1 to ensure a smooth laying surface. Simultaneously, the rear pneumatic unit begins operation. The second motor 20, installed at the bottom of the left mounting seat 19 on the left side wall of the placing boom 9, drives the second air nozzle 21 to rotate. One air outlet is horizontally facing the driving component of the placing boom 9, and the ejected gas removes dust and cools the driving component, extending the equipment's service life. The other air outlet is tilted downwards, providing auxiliary air spraying treatment to the surface of the laid concrete slurry, improving the surface condition of the slurry.

[0064] Safety Control: The position switches 22 installed on the left and right end faces of the translation frame 5 cooperate with the limit plates 23 fixed to the bottom of the left and right ends of the rigid frame 3. When the translation frame 5 moves to the set limit position, the position switches 22 contact the limit plates 23, triggering a signal to control the translation frame 5 to stop moving, preventing it from exceeding the safe range and ensuring the safe operation of the equipment.
