Description

Technical Field

[0001] This utility model relates to a track-type concrete placing machine, belonging to the field of precast concrete processing technology. Background Technology

[0002] Precast concrete products are precast concrete components manufactured and processed in a prefabrication yard. They are then transported directly to the construction site for installation. During the manufacturing process, a hollow mold is first made from slabs. Reinforcing steel bars are then placed in the hollow portion of the mold, and finally, concrete is poured into the hollow area. After drying, the slabs are removed, leaving the precast concrete product.

[0003] Existing production equipment has significant shortcomings in functional integration. Most production lines still use separate equipment to independently complete the material receiving, unloading, and placement processes. Each step requires manual transfer or the addition of intermediate buffer devices, which not only increases material loss and energy consumption but also easily causes time delays, leading to concrete slump loss and affecting construction quality. In addition, the equipment has a low degree of automation and cannot adjust process parameters in real time according to parameters such as the specifications of precast concrete products and concrete mix proportions, making it difficult to meet diverse and high-precision production needs.

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] This utility model relates to a track-mounted concrete placing boom, an automated machine for producing precast concrete products, enabling automated placement and construction of precast concrete products, such as precast concrete slabs. This placing boom can also be applied to the placement of other precast products.

[0043] like Figure 1As shown, the track-mounted concrete placing boom mainly includes a placing box girder 1 and a placing mechanism. The placing box girder 1 is a long box girder structure, and a transverse traveling mechanism 12 is set on the placing box girder 1, on which the placing mechanism is mounted. The transverse traveling mechanism 12 drives the placing mechanism to travel laterally on the placing box girder 1. The main body of the transverse traveling mechanism 12 is a traveling trolley with wheels, which are driven by a motor.

[0044] like Figure 2 , Figure 3 As shown, the concrete placement mechanism includes a main placement bin 2, a metering bin 3, and a precision placement bin 4. The main placement bin 2 is used to hold concrete material and has a large capacity. The metering bin 3 is used to measure the amount of concrete. The required volume of concrete is determined according to the specifications of the precast concrete product. The size of the metering bin 3 is adjusted accordingly to change its volume, thus measuring the required amount of material. The precision placement bin 4 is used to directly place the concrete into the mold platform 11. The main placement bin 2, metering bin 3, and precision placement bin 4 are arranged sequentially from top to bottom. The concrete in the main placement bin 2 is poured into the metering bin 3, the concrete in the metering bin 3 is poured into the precision placement bin 4, and the concrete in the precision placement bin 4 is placed into the mold platform of the precast concrete product.

[0045] In specific implementation, the discharge port at the bottom of the main concrete placement bin 2 needs to be accurately aligned with the metering bin 3; the discharge port at the bottom of the metering bin 3 needs to be accurately aligned with the precision concrete placement bin 4; to ensure that the concrete material can accurately fall into the corresponding functional bin.

[0046] like Figure 2 As shown, the main material distribution bin 2, the metering bin 3, and the precision material distribution bin 4 are all equipped with discharge ports at their lower parts for material discharge, and each has a bin door controlled by a telescopic rod 10. The opening and closing size of the discharge port is controlled by controlling the position of the bin door through the telescopic rod 10. In specific implementations, the telescopic rod 10 is usually a hydraulic telescopic rod, which enables precise control.

[0047] To achieve better concrete placement, several discharge ports are installed at the lower end of the precision concrete placement bin 4, with these ports spaced at intervals. Each discharge port's opening and closing is controlled by a bin door controlled by a telescopic rod 10. The multiple discharge ports improve the concrete placement effect and enhance the production quality of precast concrete products. Specifically... Figure 4 As shown.

[0048] This technical solution can set up multiple precision fabric bins 4, which can improve fabric production efficiency, such as... Figure 1As shown, specifically, the precision placement bin 4 and the metering bin 3 are set separately, and multiple precision placement bins 4 can be set. Concrete material is added to different precision placement bins 4 by the metering bin 3. A placement track 13 is set below the placement box girder 1 to allow the precision placement bins 4 to move on it; a placement trolley 14 is also set to drive the movement of the precision placement bins 4, and the precision placement bins 4 are mounted on the placement track 13 via the placement trolley 14. Multiple combinations of precision placement bins 4 and placement trolleys 14 are set on the placement track 13. During operation, multiple precision placement bins 4 work alternately or simultaneously, thereby improving placement efficiency. In this embodiment, a placement trolley is set for the precision placement bin 4, and the precision placement bin 4 is mounted on the placement trolley 14. The placement trolley 14 drives the precision placement bins 4 to move on the placement track 13. When the metering bin 3 releases material into the precision placement bin 4, it is necessary to ensure that the metering bin 3 is aligned with the precision placement bin 4. The efficiency of precast concrete placement is improved by setting up multiple precision placement bins 4. Since the metering bin 3 has already pre-measured the required amount of concrete as needed, the metering bin can quickly tilt and unload into the precision placement bin 4.

[0049] The fabric placing machine also includes a hydraulic control system and an electrical control system.

[0050] The main placing hopper 2 of this track-mounted concrete placing boom is used to hold a large amount of concrete. To prevent the concrete from failing to solidify, a mixing mechanism is installed inside the main placing hopper 2. During operation, the mixing mechanism agitates the concrete to prevent solidification. Specifically, the mixing mechanism includes a motor-driven mixing shaft and several mixing blades 6 mounted on the shaft. The motor is equipped with a frequency converter to control its speed, ensuring an appropriate speed for mixing the concrete.

[0051] In this track-mounted concrete placing boom, the metering chamber 3 is the mechanism for measuring concrete material. Depending on the size of the precast concrete product, the required volume of concrete varies. The size of the metering chamber 3 is adjusted accordingly to change its volume, ensuring that the required volume of material is measured precisely. Therefore, the metering chamber 3 is a detachable installation structure, allowing for the removal and replacement of different sized metering chambers as needed.

[0052] like Figure 5 , Figure 7As shown, this track-mounted concrete placing boom typically places concrete onto multiple arranged formwork platforms 11 during the production of precast concrete products. Several formwork platforms 11 are arranged, and the track-mounted concrete placing boom adjusts its position via a track system to place concrete into the formwork platforms 11. This track-mounted concrete placing boom needs to be able to travel longitudinally; correspondingly, longitudinal travel mechanisms 7 are installed at both ends of the placing beam 1. These longitudinal travel mechanisms mainly consist of traveling seats equipped with traveling wheels, which are driven by a motor.

[0053] The longitudinal movement of the track-type concrete placing boom also requires the installation of a longitudinal travel track 8. During operation, the longitudinal travel mechanism 7 drives the entire machine to move on the longitudinal travel track 8.

[0054] A concrete mixing plant 9 is installed at one end of the longitudinal travel track 8, and the concrete mixing plant 9 supplies the concrete material. Specifically, as follows... Figure 6 , Figure 7 As shown.

[0055] This track-mounted concrete placing boom can be controlled remotely or automatically via a control system.

[0056] This technical solution also discloses the working method of the track-type concrete placing machine, which uses the aforementioned track-type concrete placing machine. First, two longitudinal traveling tracks 8 are set up at a certain distance. In the area between the two longitudinal traveling tracks 8, several arranged formworks 11 are placed. The formworks 11 here act as templates, and concrete needs to be injected into the formworks 11.

[0057] The construction steps are as follows:

[0058] 1. Move the placing boom to a position below the concrete mixing plant, and move the main placing hopper 2 to the corresponding position below the discharge port of the concrete mixing plant 9.

[0059] 2. The mixer of concrete batching plant 9 discharges the material, and the mixing in the main material distribution hopper 2 is started to prevent the concrete material from solidifying.

[0060] 3. After the mixer finishes discharging the material, move the material distribution machine to position 11 on the mold table for positioning.

[0061] 4. After positioning is completed, select the appropriate placement parameters according to the different sizes of precast concrete products, and start placing.

[0062] 5. First, open the discharge port of the main fabric bin 2 and discharge the material into the metering bin 3. The capacity of the metering bin 3 is fixed.

[0063] 6. After the metering chamber 3 is full, the discharge port of the main concrete placing chamber 2 is closed; the discharge port of the metering chamber 3 is opened to discharge material into the precision placing chamber 4 until all the concrete material is placed into the precision placing chamber 4.

[0064] 7. The feeding chamber door of the precision feeding chamber 4 opens, the whole machine moves, and begins to feed material into the mold table.

[0065] 8. At the same time as the fabric is being fed, the feeding chamber door of metering chamber 3 is closed, and the feeding chamber door of main fabric chamber 2 is opened, and the second feeding of fabric into metering chamber 3 begins.

[0066] After the first precast concrete product is placed, the placing machine moves to the corresponding position according to the position of the second precast concrete product to be processed selected by the placing machine; at the same time, after the main placing hopper 2 finishes discharging, the discharge hopper door of the main placing hopper 2 is closed; the discharge hopper door of the metering hopper 3 is opened to discharge material into the precision placing hopper 4; this cycle is repeated until the placement of the entire precast concrete product on the formwork is completed; after all the concrete material in the main placing hopper has been discharged, it is sent to the concrete mixing plant for receiving.

[0067] This utility model of a track-type concrete placing machine, by setting up a main placing bin, a metering bin, and a precision placing bin, can achieve accurate metering and uniform material placement through the cooperation of the three bins, thereby improving the production efficiency of precast concrete products.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
