Technical Field

[0001] The utility model belongs to the technical field of installation equipment for precast air ducts at the rail top, and particularly relates to a movable installation equipment for precast air ducts at the rail top. Background Technique

[0002] The weight of a single component of the box-shaped precast rail top air duct is relatively large. In the current field of installing precast air ducts at the rail top, tower cranes are usually used for installation. This traditional manual operation method is complex, requires a large amount of manpower, wastes a lot of human and material resources, and has insufficient stability in a complex construction site environment, resulting in difficult installation positioning, difficult quality assurance, low construction efficiency, and the tower crane increasing the safety risks of ground construction personnel.

[0003] In addition, since the tower crane operator needs to rely on the command of ground personnel to move the rail top air duct, the installation accuracy of the precast rail top air duct is limited, and the positioning of the precast air duct is often not accurate enough, affecting the overall performance of the air duct and the quality of the project.

[0004] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies of the existing technology to improve the installation efficiency, reduce costs, and ensure construction safety and reliability. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide a movable installation equipment for precast air ducts at the rail top, which uses the method of lifting from below and horizontal fine adjustment to increase the safety and installation accuracy of the installation of precast air ducts at the rail top.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A movable installation equipment for precast air ducts at the rail top includes a chassis structure, a main body bracket, and an outer bracket; the main body bracket is fixed on the chassis structure, the outer bracket is sleeved on the upper part of the main body bracket, a steel frame is fixed on the top of the outer bracket, a plurality of sliding wheels are arranged on the top surface of the steel frame, a loading platform is placed on the top surface of the sliding wheels, and the translation range of the loading platform does not exceed the outer edge of the outer bracket; the main body bracket includes a plurality of inner corner columns arranged vertically and in a rectangular pattern and multiple inner frames fixed between the inner corner columns. An elevating oil cylinder is installed on the topmost inner frame, and the jacking end of the elevating oil cylinder is connected to the steel frame to drive the outer bracket to move up and down along the main body bracket.

[0008] Furthermore, the outer bracket includes side columns arranged in a rectangular pattern and a plurality of first reinforcing bars fixed between adjacent side columns, and the first reinforcing bars are arranged horizontally.

[0009] Further, a plurality of second reinforcing rods are also fixed between adjacent side columns. The second reinforcing rods are inclined. The first reinforcing rods and the second reinforcing rods are used to reinforce the outer bracket.

[0010] Further, the size of the loading platform is smaller than the top surface of the outer bracket. The top surface of the loading platform is not lower than the top surface of the outer bracket; the bottom surface of the loading platform is not higher than the top surface of the outer bracket; specifically, the top surface of the loading platform is not lower than the top surface of the side column or the top surface of the uppermost reinforcing rod; the height of the bottom surface of the loading platform does not exceed the height of the side column or the top surface of the uppermost reinforcing rod, so that the loading platform can only move within the range of the outer bracket.

[0011] Further, between the loading platform and the side column, or between the loading platform and the uppermost first reinforcing rod, a safety rope is connected. The safety rope is used to prevent the loading platform from falling off. Within the normal moving range of the loading platform, the safety rope is in a slack state.

[0012] Further, one end of the safety rope is fixed to the side column or the uppermost first reinforcing rod of the loading platform through a rope fastener, and the other end of the safety rope is connected to the bottom surface of the loading platform.

[0013] Further, the safety rope is at least arranged on two sides of the loading platform.

[0014] Further, a plurality of inner pulleys that can move along the inner corner columns are arranged inside the outer bracket to increase the stability when the outer bracket is lifted and lowered.

[0015] Further, a plurality of telescopic cylinders are also installed on the chassis structure. The telescopic ends of the telescopic cylinders face downward and are installed with casters; the telescopic cylinders are evenly arranged on the chassis structure, so that the chassis structure can be stably lifted. After the telescopic cylinders extend and lower the casters, the equipment can be pushed.

[0016] Further, the chassis structure includes outer corner columns arranged on the outer circle of the inner corner columns, inner connecting pipes connected between adjacent inner corner columns, outer connecting pipes connected between the outer corner columns, and short middle connecting pipes and long middle connecting pipes fixed between adjacent inner connecting pipes and outer connecting pipes.

[0017] The frame structure of the present utility model is designed firmly and can achieve a strong support for prefabricated specified air duct unit sections; by lifting the outer bracket with a lifting oil cylinder, the height adjustment of the prefabricated track top air duct unit section can be realized. At the same time, a loading platform supported by sliding wheels is designed on the top surface of the outer bracket, and the translation of the prefabricated specified air duct unit section can be realized, so as to finely adjust the horizontal position of the prefabricated track top air duct unit section without moving the chassis structure, achieve precise positioning support for the track top prefabricated air duct, and assist workers to complete the installation of the track top prefabricated air duct faster and better.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] like Figures 1 to 6 As shown, a movable rail-top prefabricated air duct installation device includes a chassis structure 100, a main frame 200 and an outer bracket 300; the chassis structure 100 is used to support on a working surface, thereby supporting the entire structure;

[0030] The main frame 200 is fixed on the chassis structure 100, the outer bracket 300 is sleeved on the upper part of the main frame 200, a steel frame 303 is fixed on the top of the outer bracket 300, a plurality of sliding wheels 304 are arranged on the top surface of the steel frame 303, a loading platform 301 is placed on the top surface of the sliding wheels 304, and the translation range of the loading platform 301 does not exceed the outer edge of the outer bracket 300; the main frame 200 includes a plurality of inner corner columns 201 arranged vertically and in a rectangular arrangement and fixed on the inner corner columns 20 A multi-layer inner frame 202 is provided in a room, and a lifting cylinder 400 is installed on the uppermost inner frame 202. The lifting end of the lifting cylinder 400 is connected to the steel frame 303, driving the outer bracket 300 to move up and down along the main bracket 200, so as to adjust the vertical position of the prefabricated rail-top air duct during installation and increase the installation accuracy. The sliding wheel 304 can be a universal wheel or a directional wheel. Considering that the equipment only needs to push the prefabricated rail-top air duct along the extension direction of the rail-top air duct when in use, the sliding wheel 304 uses a directional wheel.

[0031] Furthermore, the lifting cylinder 400 may be one or more, such as Figures 1 - 3As shown in the figure, when using a single lifting oil cylinder 400, it is advisable to install it at the center of the main bracket 200 and the steel frame 303; if there are multiple oil cylinders, these oil cylinders should be evenly distributed; in order to facilitate the connection between the steel frame 303 and the lifting oil cylinder 400, a cylinder connecting piece 305 is fixed on the bottom surface of the steel frame 303, and the jacking end of the lifting oil cylinder 400 is directly fixed to the cylinder connecting piece 305. In order to further improve the installation accuracy, the lifting oil cylinder 400 can be a servo oil cylinder.

[0032] Furthermore, as Figure 1 、 Figure 2 、 Figure 5 shown, the outer bracket 300 includes side columns 309 arranged in a rectangle and a number of first reinforcing rods 310 and second reinforcing rods 311 fixed between adjacent side columns 309. The first reinforcing rods 310 are horizontally arranged, and the second reinforcing rods 311 are obliquely arranged. The size of the loading platform 301 is smaller than the size of the rectangle formed by the side columns 309. Thus, the gap between the side edge of the loading platform 301 and the side columns 309 is the movable distance of the loading platform 301; since the lengths of the prefabricated track top air duct unit sections may be different, each prefabricated track top air duct unit section can be supported and lifted by one or more of this equipment, and the translation of the position of the prefabricated specified air duct unit section can also be carried out simultaneously.

[0033] Furthermore, as Figure 1 、 Figure 3 shown, the top surface of the loading platform 301 is not lower than the top surface of the side columns 309 or the top surface of the topmost first reinforcing rod 310, so that this equipment can also be used when the prefabricated track top air duct unit section exceeds the range of the top surface of the outer bracket 300; the bottom surface height of the loading platform 301 does not exceed the top surface height of the side columns 309 or the topmost reinforcing rod; actually, the topmost reinforcing rod or side column 309 is used as a baffle 302 to limit the movement of the loading platform 301, and its function is to limit the maximum range of movement of the loading platform 301 and prevent the loading platform 301 from sliding out and falling in the horizontal direction; preferably, the loading platform 301 is slightly smaller than the size of the prefabricated track top air duct, that is, the periphery of the prefabricated track top air duct can extend beyond the loading platform 301, which requires the top surface of the loading platform 301 to exceed the top surface of the side columns 309 or the top surface of the topmost first reinforcing rod 310.

[0034] Furthermore, as Figure 3 、 Figure 6 shown, between the loading platform 301 and the side columns 309, or between the loading platform 301 and the topmost first reinforcing rod 310, they are connected by a safety rope 306. Within the normal movement range of the loading platform 301, the safety rope 306 is in a slack state. The safety rope 306 can prevent the loading platform 301 from falling and hurting people, and the safety rope 306 can be made of nylon rope or steel wire rope.

[0035] Furthermore, asFigure 3 , Figure 6 As shown, one end of the safety rope 306 is fixed to the side post 309 or the first reinforcing rod 310 at the uppermost part of the load platform through a rope fastener 307, and the other end of the safety rope 306 is connected to the bottom surface of the load platform 301. Preferably, a rope loop 308 is welded or a swivel bolt is installed on the bottom surface of the load platform 301. A buckle is fixed at the other end of the safety rope 306, and the safety rope 306 is connected to the load platform 301 with the buckle. The safety rope 306 is disposed on at least two sides of the load platform 301, such as adjacent sides or opposite sides. Preferably, the safety rope 306 is connected to 3 or 4 sides of the load platform 301, which can prevent the load platform 301 from accidentally tipping over.

[0036] Further, as Figure 6 shown, a plurality of inner pulleys 203 that can travel along the inner corner columns 201 are provided inside the outer bracket 300. Each inner corner column 201 is correspondingly provided with an inner pulley 203. Orientation is carried out by using the inner pulleys 203, which ensures that the main body bracket 200 and the outer bracket 300 do not relatively shake during the up and down movement and the overall stability of the equipment.

[0037] Further, as Figure 1 , Figure 4 shown, the chassis structure 100 includes outer corner columns 101 arranged on the outer circle of the inner corner columns 201, inner connecting pipes 102 connected between adjacent inner corner columns 201, outer connecting pipes 103 connected between the outer corner columns 101, and short middle connecting pipes 104 and long middle connecting pipes 105 fixed between the adjacent inner connecting pipes 102 and outer connecting pipes 103. In this embodiment, 4 inner corner columns 201 and 4 outer corner columns 101 are adopted, that is, a total of 8 support corner columns are provided in the chassis structure 100 to ensure the firmness of the chassis structure 100 during operation.

[0038] Further, a plurality of telescopic cylinders 111 are also installed on the chassis structure 100. The telescopic ends of the telescopic cylinders 111 face downward and are equipped with casters. The telescopic cylinders 111 are evenly arranged on the chassis structure, so that the chassis structure 100 can be smoothly lifted. The casters are directional casters. During use, it is necessary to cooperate with the rails installed on the ground. The telescopic cylinders 111 are oil cylinders, and the telescopic cylinders 111 and the lifting oil cylinder 400 are controlled by a on-site hydraulic pump station. Specifically, as Figure 4As shown, mounting plates 110 are also installed on both sides of the chassis structure 100 with the long middle connecting pipe 105 installed thereon. The cylinder body of the telescopic cylinder 111 is installed on the mounting plate 110. When the equipment needs to be moved, start the telescopic cylinder 111 to make it extend, so that the casters land on the track and the inner corner columns 201 and the outer corner columns 101 are suspended, and the whole equipment can be moved. Manually push the equipment directly along the track. After moving into place, control the telescopic cylinder 111 to retract, retract the casters into the chassis structure 100, and the inner corner columns 201 and the outer corner columns 101 fall back to the ground to achieve the purpose of fixing the equipment.

[0039] Before the equipment is put into use in place, place the prefabricated air duct on the track top on the loading platform 301 through a crane or tower crane. Note that when placing the prefabricated air duct on the track top, it is necessary to cooperate with manual precise positioning to accurately place it directly below the installation position of the air duct on the track top. Then, control the telescopic cylinder 111 through the hydraulic pump station to make the casters expose the chassis structure 100, support the whole equipment, the inner corner columns 201 and the outer corner columns 101 are suspended, and the casters bear the whole weight. At this time, the equipment can be pushed along the track to the general position where the prefabricated air duct on the track top needs to be installed. After reaching the position, control the telescopic cylinder 111 to retract through the hydraulic pump station, retract the casters, make the inner corner columns 201 and the outer corner columns 101 land, and fix the position of the equipment. Next, the outer bracket 300 can be moved up and down along the main bracket 200 to a suitable height by adjusting the lifting cylinder 400. Then, roll and adjust the position of the loading platform 301 through the sliding wheel 304, and manpower can easily push the unit section of the prefabricated air duct on the track top to finely adjust the position in the direction parallel to the track, and finally accurately move the unit section of the prefabricated air duct on the track top to the installation position for installation.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
