[0001] The utility model relates to the technical field of prefabricated component construction, in particular to a cast-in-situ curbstone mould hoisting and transfer device. Background Art

[0002] The cast-in-place curbstone mold is a mold used to make curbstones at horse paths and curbstones on both sides of canal roads by casting in place. The curbstone production process is generally completed by casting in place on a vibrating platform and then transferred to a maintenance area for centralized storage.

[0003] For water conservancy hub projects, the volume of various prefabricated concrete components is much larger and they need to be transferred through transfer equipment. At present, the most commonly used method is to transfer by flatbed trucks. However, during the use of flatbed trucks, manual loading of materials on the vibrating platform is required, and unloading in centralized maintenance areas is required. The manpower requirements are extremely high, and the production efficiency is affected by limited manpower, so the manpower input has to be increased, pushing up the project cost.

[0004] The use of specialized lifting equipment increases the cost of this work and requires planning of construction routes and space, which makes the requirements even higher.

[0005] In order to solve the above problems, it is necessary to make improvements based on the traditional cart transfer so that the loading and unloading processes can be more labor-saving and thus improve efficiency. Utility Model Content

[0028] Next, through specific embodiments, the technical solutions of the present utility model will be further described in detail.

[0029] As Figure 1 and Figure 2 shown, a hoisting and transferring device for a cast-in-place curbstone mold includes a trolley 2 and a hoisting mechanism 1 arranged at the front end of the trolley.

[0030] The trolley 2 includes a handrail 21, a frame 22 and traveling wheels 23. The hoisting mechanism 1 is installed at the front end of the frame 22. The trolley 2 is the simplest structure after removing redundant structures. The main part of the frame is an inverted triangle, and the vehicle weight is reduced through structural design to lighten the labor burden. The traveling wheels are rubber wheels, and the contact with the ground is more stable, reducing the risk brought by vibration.

[0031] The hoisting mechanism 1 includes a cross bar 11, two longitudinal bars 12, four hanging chains 13, a first hook part 14, a second hook part 15, two movable rods 16 and a movable sleeve 17.

[0032] The cross bar 11 is fixed at the front end of the trolley 2, and both sides of the front end of the cross bar 11 extend beyond the whole frame 22 as the suspension area for hoisting the longitudinal bars.

[0033] The middle parts of the tops of the two longitudinal bars 12 are respectively hinged to the two ends of the cross bar 11, specifically through circular rings, forming a suspension structure.

[0034] One hanging chain 13 is arranged at the front end and the rear end of each longitudinal bar 12, totaling 4 hanging chains 13. The hanging chains are iron chains, providing suspension support. At the same time, the main function of the hanging chain 13 is to provide a certain amount of movement, so that the operation space of the first hook part 14 and the second hook part 15 is larger.

[0035] The first hook part 14 is parallel to the cross bar 11 and is located at the rear end of the vertical bar 12. The first hook part 14 is connected to the lower ends of two vertical chains 14 at the rear ends of the two vertical bars 12. Specifically, in this embodiment, the first hook part 14 is an angle iron. One side of the angle iron is the top side which is connected to the vertical chain, and the other side serves as an outer protection side. A hook 18 is arranged inside the outer protection side. The hook 18 and the top side form a bayonet structure.

[0036] On the opposite side, the second hook part 15 is parallel to the cross bar 11 and is located at the front end of the vertical bar 12. The second hook part 15 is connected to the lower ends of two vertical chains 14 at the front ends of the two vertical bars 12. In this embodiment, the second hook part 15 has the same structure as the first hook part 14 but in the opposite direction. The openings of the formed bayonet structures face each other, forming a pair of clamping structures as shown in the figure.

[0037] One end of each of the two movable bars 16 is fixed to the first hook part 14, and the movable sleeve 17 is fixed to the second hook part 15. The movable bar 16 and the movable sleeve 17 are in socket fit, serving as the locking bolt structure of the two hook parts. Generally, the length of the movable bar is greater than the effective hanging span of the first hook part and the second hook part to ensure safety and prevent unhooking. The front end of the movable bar 16 and the socket surface of the movable sleeve 17 are both set as rough surfaces, having an anti-slip effect to avoid easily separating from each other and ensuring the safety of the mold suspension.

[0038] In a preferred embodiment, a movable anti-detaching pin is arranged at the front end of the movable bar. After the socketing is completed, the anti-detaching pin is inserted to prevent separation from each other.

[0039] The corresponding curbstone mold is a box-shaped structure with an open top and has edges at the top all around. In this embodiment, the first hook part 14 and the second hook part 15 formed are clamped with the edges of the curbstone mold to complete the hoisting of the curbstone mold.

[0040] During specific use, only need to operate the movable bar 16 and the movable sleeve 17 to separate a certain distance, so that the distance between the two hook parts is greater than the width of the curbstone mold. Then, respectively clamp the first hook part and the second hook part with the edges on both sides of the curbstone mold. After the hanging connection is completed, lift the mold, transfer the curbstone mold from the vibrating platform to the curing area. After arriving at the destination, lower the curbstone mold to the designated position, and then operate the movable bar 16 and the movable sleeve 17 to separate again, and put down the curbstone mold. Repeat the above process to complete the transfer of a batch of curbstone molds.

[0041] An experiment was conducted on Construction Section 1 of the Water Conveyance and Irrigation Project of the Xixiayuan Water Control Project in Henan Province. There are specifications for the curb stones at the horse paths of the channel project and the curb stones on both sides of the canal road in this project. The engineering quantity of the curb stones at the horse paths is 18.96 km, and the engineering quantity of the curb stones on both sides of the canal road is 24.266 km. Both types of curb stones are prefabricated centrally in the prefabrication yard. The prefabrication molds are made of plastic-steel molds. The hoisting and transfer of the cast-in-place curb stones adopt the hoisting and transfer device for the cast-in-place curb stone molds. This device facilitates the hoisting and transfer of the cast-in-place curb stone molds to the precast component curing area or the centralized storage area. It is simple and convenient to operate, and remarkable achievements have been made in terms of cost control, construction progress, etc.

[0042] Finally, it should be noted that the above has made a detailed description of the preferred embodiment of this patent. However, this patent is not limited to the above embodiment. Within the scope of knowledge possessed by ordinary technicians in the art, various changes can also be made without departing from the purpose of this patent.
