Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a walking arc hanging basket for slip form construction of a shallow round silo. Background Technique

[0002] In the construction field, with the continuous improvement of the industrialized, mechanized and intelligent production modes, the original traditional construction technology cannot meet people's requirements for quality, efficiency and environmental protection. The degree of construction mechanization is an important indicator to measure the construction industry level of a country. The use of machinery in building construction plays a significant role in reducing heavy physical labor, saving labor force and accelerating the project progress. With the rapid development of the construction industry, the degree of construction mechanization is also increasing year by year, promoting the continuous improvement of construction technology and further development of construction mechanization.

[0003] A shallow round silo, also known as a short round silo, is a cylindrical above-ground grain silo with a ratio of silo height to diameter less than 1.5. Most of them are flat-bottom silos, and the main body of the silo wall is mostly made of reinforced concrete structure. During the slip form construction process of the shallow round silo, construction workers need to carry out high-altitude operations such as silo wall inspection, finishing and watering maintenance. Currently, the construction operation is generally carried out through a slip form construction hanging frame for the shallow round silo, that is, a steel pipe combined construction frame body hanging on the steel pipe truss of the slip form operation platform along the inner and outer silo walls of the shallow round silo. However, setting up the hanging frame is time-consuming and laborious, with high costs, and a large volume, increasing the weight of the slip form lifting frame. The mobile hanging basket is an excellent alternative form of the slip form construction hanging frame for the shallow round silo that is more convenient and faster to move and meets the requirements of intelligent construction.

[0004] Chinese Patent with application number 202110005250.4 discloses a horizontally mobile hanging basket, including: a track, a pulley, a hanging basket body and a driving component. A plurality of hanging columns are provided on the hanging basket body, the pulley is arranged at the top of the hanging column, the pulley is slidably arranged on the track, and the driving component is used to drive the pulley to move along the track. The track is an I-beam. During use, the pulley is prone to falling off, posing a safety hazard; the above structure is applicable to the construction of honeycomb aluminum plates or fireproof coatings at the bottom of high-rise cantilever structures and is not suitable for the construction of circular buildings and structures.

[0017] As Figure 1 、 Figure 2As shown in the figure, for the arc-shaped hanging basket used in the slip form construction of the shallow silo, arc-shaped single beam guide rails 1 are installed on both the inner and outer silo walls 8 of the shallow silo below the steel pipe truss 9 of the slip form operation platform. There is an anti-derailment edge 11 at the bottom of the single beam guide rail 1. Two traveling trolleys 2 are installed on each single beam guide rail 1. Both traveling trolleys 2 use non-standard H-shaped double-sided wheels. A hanging basket 3 is hung below each traveling trolley 2 through a steel belt 33 and bolts. A horizontal telescopic guide wheel mechanism 4 is provided on one side of each hanging basket 3 close to the silo wall of the shallow silo. The horizontal telescopic guide wheel mechanism 4 includes an outer sleeve 41 fixed on the hanging basket 3, an inner sleeve 42 that can telescopically move within the outer sleeve, and a guide wheel 43 provided at the end of the inner sleeve. A mechanical spring (not shown in the figure) is provided at the end of the inner sleeve extending into the outer sleeve to achieve the telescopic movement of the inner sleeve within the outer sleeve.

[0018] During normal operation, the guide wheel 43 abuts against the silo wall of the shallow silo, and the mechanical spring is in a slightly compressed state. Since the distance between the hanging basket and the silo wall of the shallow silo is not exactly the same, there is a deviation of approximately 10 cm. When the distance between the hanging basket and the silo wall of the shallow silo is smaller than the designed value, the silo wall of the shallow silo squeezes the guide wheel 43, and the inner sleeve 42 is squeezed into the outer sleeve, and the mechanical spring is further compressed. By selecting a suitable mechanical spring, it is ensured that this squeezing force only compresses the spring, changing the telescopic amount of the inner sleeve within the outer sleeve 41, without affecting the stability of the hanging basket. When the distance between the hanging basket and the silo wall of the shallow silo is larger than the designed value, the compressed mechanical spring releases the pressure, pushing the inner sleeve 42 out of the outer sleeve, so as to ensure that the guide wheel 43 always adheres tightly to the silo wall of the shallow silo.

[0019] There is an anti-derailment edge 11 at the bottom of the single beam guide rail 1. Both traveling trolleys 2 use non-standard H-shaped double-sided wheels. The H-shaped double-sided wheels of the traveling trolleys cooperate with the anti-derailment edge 11 to prevent the traveling trolleys from derailing.

[0020] As Figure 3 shown, two holes are drilled at the upper wings of each single beam guide rail 1. The steel pipe truss 9 of the slip form operation platform is bolted to the single beam guide rail 1 through a U-shaped snap ring 12. Fixing points are provided below each steel pipe truss of the slip form operation platform.

[0021] The two traveling trolleys 2 are respectively a driving trolley and a driven trolley. The driving trolley is driven by a DC motor. The power supply of the DC motor is 48v, which is composed of 4 12v batteries connected in series and installed in two groups on both sides of the hanging basket. The DC motor is installed on the traveling trolley 2 through a mounting plate. A control switch is installed on one side of the hanging basket 3. The control switch is provided with forward, reverse, and stop buttons. Press the forward button, the DC motor rotates forward to control the hanging basket to move forward; press the reverse button, the DC motor rotates in reverse to control the hanging basket to move backward; when the hanging basket moves to a suitable position, press the stop button, the hanging basket stops. Before the hanging basket restarts, press the stop button again for reset, and then press the forward or reverse button, as Figure 4 shown.

[0022] The designed length of the hanging basket is 3m, the width is 1m, the height of the side close to the silo wall of the shallow silo is 1m, and the height of the outer side and the two short sides is 1.5m. The main frame of the hanging basket is welded with square steel of 40×60×2.0. In the middle part, square steel of 40×40×2.0 is welded with the square steel of the main frame, and the spacing is 100mm. The bottom of the hanging basket 3 is covered with thin iron sheet, which is turned up 200mm along the perimeter as a baffle. Battery devices 31 are arranged at the two short sides of the hanging basket 3.

[0023] A pull rod 32 is arranged above the hanging basket 3. The pull rod is preferably square steel of 40×80×2.5. The shape of the pull rod is gate-shaped. The two free ends are welded to the two short sides of the hanging basket 3. The two ends of the cross bar of the pull rod 32 are connected to the traveling trolley 2.

[0024] One hanging point is arranged on each of the driving trolley and the driven trolley. A steel belt 33 is bent and wrapped around the pull rod 32 above the hanging basket. The two sides of the steel belt 33 are welded to the pull rod 32. The upper end of the steel belt that does not wrap the pull rod 32 is connected to the traveling trolley 2 by two M10 bolts 34, as Figure 5 shown. The steel belt 33 is preferably 3mm thick and 100mm wide.

[0025] Furthermore, horizontal telescopic guide wheel mechanisms 4 are arranged at both inner ends of each hanging basket 3 close to the silo wall of the shallow silo, which is more conducive to keeping the hanging basket balanced during movement.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
