Description

Technical Field

[0001] The present invention relates to an orbital concrete placing boom and a working method thereof, belonging to the technical field of concrete precast processing. Background Art

[0002] Concrete precast products are concrete precast components produced and processed in a precast yard, and the concrete precast products are directly transported to the construction site for installation. When processing concrete precast products, a hollow model is first made of boards. After steel bars are arranged in the hollow part of the model, the hollow part is filled with concrete material. After drying, the boards are removed, and what remains is the concrete precast product.

[0003] There are obvious short - comings in the functional integration of existing production equipment. Most production lines still use split - type equipment to independently complete the processes of receiving materials, discharging materials, and placing materials. Manual transfer or additional intermediate buffer devices are required for each link, which not only increases material loss and energy consumption, but also easily causes time delay, resulting in the loss of concrete slump and affecting the construction quality. In addition, the degree of equipment automation is low, and it is impossible to adjust process parameters in real time according to parameters such as the specifications of concrete precast products and concrete mix ratios, making it difficult to meet the diverse and high - precision production requirements.

[0021] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] The present invention is a rail-type concrete placing boom, which is an automated machine for producing concrete precast products and can realize the automated placing construction production of concrete precast products, such as concrete precast slabs. This placing boom can also be applied to the placing of other precast products.

[0024] As Figure 1 shown, this rail-type 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. A transverse traveling mechanism 12 is arranged on the placing box girder 1, and the placing mechanism is arranged on the transverse traveling mechanism. The transverse traveling mechanism 12 drives the placing mechanism to travel transversely on the placing box girder 1. The main body of the transverse traveling mechanism 12 is a traveling trolley with traveling wheels, and the traveling wheels are driven by a motor.

[0025] As Figure 2 、 Figure 3As shown in the figure, the cloth feeding mechanism includes a main cloth feeding bin 2, a metering bin 3 and a precise cloth feeding bin 4. The main cloth feeding bin 2 is used to hold concrete materials and has a relatively large capacity. The metering bin 3 is used to measure the amount of concrete. The metering bin 3 determines the required amount of concrete according to the specifications of the concrete precast products, and correspondingly adjusts the size of the metering bin 3 to change the volume of the metering bin 3, so as to measure the amount of materials required. The precise cloth feeding bin 4 is used to directly feed and cloth the concrete into the mold table 11. The main cloth feeding bin 2, the metering bin 3 and the precise cloth feeding bin 4 are arranged correspondingly from top to bottom. The concrete in the main cloth feeding bin 2 is put into the metering bin 3, the concrete materials in the metering bin 3 are put into the precise cloth feeding bin 4, and the concrete materials in the precise cloth feeding bin 4 are fed and cloth into the mold of the concrete precast product.

[0026] In the specific implementation, it is necessary to accurately set the discharge port at the lower part of the main cloth feeding bin 2 corresponding to the metering bin 3; accurately set the discharge port at the lower part of the metering bin 3 corresponding to the precise cloth feeding bin 4; ensure that the concrete materials can accurately fall into the corresponding functional bin.

[0027] As Figure 2 shown in the figure, discharge ports are provided at the lower parts of the main cloth feeding bin 2, the metering bin 3 and the precise cloth feeding bin 4 for discharging materials, and a bin door controlled by a telescopic rod 10 is provided. 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 the specific implementation, the telescopic rod 10 is usually a hydraulic telescopic rod, and precise control can be achieved through the hydraulic telescopic rod.

[0028] In order to achieve a better cloth feeding effect, a number of material discharge ports are provided at the lower end of the precise cloth feeding bin 4, and these material discharge ports are arranged at intervals. Each material discharge port uses a bin door controlled by a telescopic rod 10 to control the opening and closing size of the material discharge port. The setting of multiple material discharge ports can achieve a better cloth feeding effect and improve the production quality of concrete precast products. Specifically as Figure 4 shown in the figure.

[0029] In this technical solution, multiple precise cloth feeding bins 4 can be set, which can improve the cloth feeding efficiency, as Figure 1As shown in the figure, specifically, the precise concrete bin 4 and the metering bin 3 are separately arranged, and multiple precise concrete bins 4 can be set. The metering bin 3 fills the concrete into different precise concrete bins 4 respectively. A cloth track 13 is arranged below the cloth box girder 1 to enable the precise concrete bin 4 to move on it; a cloth trolley 14 is also arranged to drive the movement of the precise concrete bin 4, and the precise concrete bin 4 is installed on the cloth track 13 through the cloth trolley 14. A combination of multiple precise concrete bins 4 and cloth trolleys 14 is arranged on the cloth track 13. During operation, multiple precise concrete bins 4 work alternately or simultaneously in sequence, thereby improving the cloth efficiency. In this embodiment, a cloth trolley is provided for the precise concrete bin 4, and the precise concrete bin 4 is installed on the cloth trolley 14. The cloth trolley 14 drives the precise concrete bin 4 to move on the cloth track 13. When the metering bin 3 discharges materials into the precise concrete bin 4, it is necessary to ensure that the metering bin 3 is aligned with the precise concrete bin 4. By setting multiple precise concrete bins 4, the cloth construction efficiency of concrete prefabricated products is improved. Since the metering bin 3 has already measured the required concrete in advance as needed, the metering bin can quickly discharge the materials obliquely into the precise concrete bin 4.

[0030] This cloth machine further includes a hydraulic control system and an electrical control system.

[0031] The main cloth bin 2 of this rail-type concrete cloth machine is used to hold a large amount of concrete. In order to prevent the concrete from solidifying, a stirring mechanism needs to be arranged in the main cloth bin 2. During operation, the stirring mechanism performs stirring work, and the stirring mechanism stirs the concrete to prevent the concrete from solidifying. Specifically, the stirring mechanism includes a stirring shaft driven by a motor and several stirring blades 6 arranged on the stirring shaft. Here, a frequency converter is set for the motor to control the rotation speed, and an appropriate rotation speed is used to stir the concrete.

[0032] In this rail-type concrete cloth machine, the metering bin 3 is a mechanism for measuring concrete. According to different sizes of concrete prefabricated products, the required amount of concrete is different, and the size of the metering bin 3 is correspondingly adjusted to change the volume of the metering bin 3, so as to measure as much material as needed. Therefore, the metering bin 3 has a detachable installation structure, and different sizes of metering bins 3 can be disassembled and replaced for this rail-type concrete cloth machine according to actual needs.

[0033] Such as Figure 5 、 Figure 7As shown in the figure, when the gantry concrete placer is used for placing concrete precast products, it usually places concrete on a number of form tables 11 arranged in a row. A number of form tables 11 are arranged, and the gantry concrete placer adjusts its position through the track setting to place concrete into the form table 11. The gantry concrete placer needs to be able to travel longitudinally. Correspondingly, longitudinal traveling mechanisms 7 are provided at both ends of the placing box girder 1. Here, the longitudinal traveling mechanism is mainly a traveling seat provided with traveling wheels, and the traveling wheels are driven by motors to rotate.

[0034] For the longitudinal traveling of the gantry concrete placer, a longitudinal traveling track 8 also needs to be provided. During operation, the longitudinal traveling mechanism 7 drives the whole machine to move on the longitudinal traveling track 8.

[0035] A concrete mixing station 9 is provided at one end of the longitudinal traveling track 8 to supply concrete materials. Specifically, as shown in Figure 6 、 Figure 7 the figure.

[0036] The gantry concrete placer can be controlled by remote control or automatically controlled through a control system.

[0037] In this technical solution, the working method of the gantry concrete placer is also disclosed, using the above-mentioned gantry concrete placer. First, two longitudinal traveling tracks 8 are provided at a certain distance apart, and a number of arranged form tables 11 are placed in the area between the two longitudinal traveling tracks 8. Here, the form table 11 serves as a formwork, and concrete materials need to be injected into the form table 11.

[0038] The construction steps are as follows. 1. Drive the placer under the concrete mixing station, and move the main placing bin 2 to the corresponding position below the discharge opening of the concrete mixing station 9.

[0039] 2. The mixer of the concrete mixing station 9 discharges materials, and the agitation in the main placing bin 2 is started to prevent the concrete materials from solidifying.

[0040] 3. After the mixer finishes discharging materials, drive the placer to the position of the form table 11 for positioning.

[0041] 4. After the positioning is completed, pre-select the corresponding appropriate placing parameters according to the concrete precast products of different sizes, and start placing.

[0042] 5. First, open the discharge opening of the main placing bin 2 to discharge materials into the metering bin 3. The capacity of the metering bin 3 is a fixed quantity.

[0043] 6. After the metering bin 3 is full, close the discharge opening of the main placing bin 2; open the discharge opening of the metering bin 3 to discharge materials into the precise placing bin 4 until all the concrete materials are discharged into the precise placing bin 4.

[0044] 7. The discharge bin door of the precise batching bin 4 is opened, and the whole machine moves to start discharging and distributing materials into the mold table.

[0045] 8. While distributing materials, the discharge bin door of the metering bin 3 is closed, and the discharge bin door of the main batching bin 2 is opened to start the second discharging into the metering bin 3.

[0046] After the distribution of the first precast concrete product is completed, according to the position of the second precast concrete product to be processed selected by the distributer, the distributer moves to the corresponding position; at the same time, after the discharging of the main batching bin 2 is completed, the discharge bin door of the main batching bin 2 is closed; the discharge bin door of the metering bin 3 is opened to discharge materials into the precise batching bin 4; and so on in a cycle until the distribution of all the precast concrete products on the mold table is completed; after all the concrete materials in the main batching bin are discharged, go to the concrete mixing station to receive materials.

[0047] The rail - type concrete distributer of the present invention, by setting the main batching bin, the metering bin and the precise batching bin, through the mutual cooperation of the three bins, can achieve precise metering and uniform distribution, and improve the production efficiency of precast concrete products.
