[0002] During the equipment installation and construction of engineering projects, some device frames have small or no reserved holes on the top, which results in the horizontal equipment with high installation elevation, large volume and heavy weight installed in the frame not being able to be installed by a crane at one time. Instead, it is necessary to move the equipment from outside the frame to the equipment foundation inside the frame and then hoist it into place. The commonly used installation technology is to make a large steel structure bracket as a load-bearing track to move the equipment above the equipment foundation, and then use a crane (with reserved holes on the top) or a jack (without reserved holes on the top) to install the equipment in place.

[0003] However, the installation method of making large steel structure brackets as load-bearing rails requires the production of large and long-distance load-bearing steel brackets, which requires a lot of materials and has high production and installation costs, which reduces the installation efficiency.

[0039] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0040] Embodiment 1

[0041] In order to solve the existing problems of equipment installation and construction in engineering projects, it is generally necessary to make large steel structure brackets as load-bearing tracks to move the equipment to the equipment foundation. The installation cost is high, and the friction between the equipment and the steel structure bracket is large during the movement, and the moving position is not convenient enough. Please refer to Figure 1-Figure 2 The present invention provides a large-scale horizontal equipment layered mobile installation device, including a pillow path 1 and a layer of roller assembly located on the pillow path 1, a movable bracket 3 is provided on the first layer of roller assembly, and a second layer of roller assembly is provided on the top of the movable bracket 3 for placing the horizontal equipment 4 to be moved and installed, the first layer of roller assembly and the second layer of roller assembly each include a plurality of roller bodies 2, and both sides of the first layer of roller assembly and the second layer of roller assembly are provided with limit plates 5; a self-lubricating assembly is provided inside the roller body 2, and the self-lubricating assembly includes a plurality of equally spaced oil supply units 6 for supplying oil to the surface of the roller body 2, an oil storage tank 7, and a refueling unit 8 for adding the lubricating oil in the oil storage tank 7 to the oil supply unit 6.

[0042] like Figure 3-Figure 4As shown, the oil supply unit 6 includes an oil supply tank 601, and a plurality of pressurized pipes 602 and oil outlet tubes 603 are arranged around the oil supply tank 601. A piston 604 is arranged in the pressurized pipe 602, and a piston rod 605 is fixedly arranged on the piston 604. A wedge block 606 is fixedly arranged at the end of the piston rod 605, which is used to squeeze the piston rod 605 after being subjected to force so that the lubricating oil flows from the oil outlet tube 603 to the surface of the roller body 2. A first spring 607 is sleeved on the piston rod 605, and one end of the first spring 607 is fixedly connected to the piston 604, and the other end is fixedly connected to the inner wall of the roller body 2; a through hole for the wedge block 606 and the oil outlet tube 603 to pass through is arranged on the surface of the roller body 2, and the wedge block 606 protrudes from the surface of the roller body 2. The lubricating oil can be well stored in the oil supply bin 601. During the rolling process of the roller body 2, the wedge block 606 in contact with the pillow path 1, the movable bracket 3 or the horizontal equipment 4 is squeezed and moves into the roller body 2, driving the piston rod 605 and the piston 604 to move. At this time, the first spring 607 is compressed, and pressure is applied to the oil supply bin 601 through the piston 604. The lubricating oil in the oil supply bin 601 slowly penetrates into the surface of the roller body 2 through the oil outlet tube 603. No additional power equipment is required. As the roller body 2 continues to roll, when the wedge block 606 is separated from the pillow path 1, the movable bracket 3 or the horizontal equipment 4, it is reset under the action of the first spring 607 and stops seeping. As the roller body 2 continues to roll, the wedge block 606 in the new position is squeezed by the pillow path 1, the movable bracket 3 or the horizontal equipment 4, and the lubrication operation is performed again.

[0043] The present invention also provides a method for installing and moving large-scale horizontal equipment in layers, comprising the following steps:

[0044] S1, placing the horizontal equipment 4 on the second-layer roller assembly through the lifting equipment;

[0045] S2, applying a thrust to the movable bracket 3 to make it move on a layer of roller assembly, and drive the roller body 2 to roll;

[0046] In the rolling process of the roller body 2, the bottom of the movable bracket 3 and the top of the pillow track 1 apply pressure to the wedge block 606 at the corresponding position, so that the lubricating oil in the oil supply tank 601 seeps out to the surface of the roller body 2 through the oil outlet tube 603 to achieve self-lubrication, and the lubricating oil in the oil storage tank 7 is added to the oil supply unit 6 through the oiling unit 8 to ensure that the oil level in the oil supply tank 601 is always within the set range;

[0047] S3, after the mobile bracket 3 moves to the designated position on the first layer, the mobile bracket 3 is fixed, and then a thrust is applied to the horizontal device 4 to make it move on the second layer roller assembly, and the second layer is continued to move, and the roller body 2 is driven to roll;

[0048] In the rolling process of the roller body 2, the bottom of the horizontal device 4 and the top of the mobile bracket 3 apply pressure to the wedge block 606 at the corresponding position to achieve self-lubrication of the roller body 2;

[0049] S4. After the horizontal equipment 4 is moved to the installation position on the second floor, the installation index of the horizontal equipment 4 is adjusted to meet the design requirements, and the installation of the horizontal equipment 4 is completed.

[0050] The horizontal equipment 4 is installed in place by a layered moving method, which is simple and effective, can be disassembled and reused, and saves costs compared to the traditional production of large-scale integrated tooling brackets. The horizontal equipment 4 can maintain slow and stable movement, and can perform more delicate operations. The horizontal equipment 4 can be accurately installed in a predetermined position. The oil supply unit 6 is used to make the roller body 2 have a self-lubricating function. When the roller body 2 is working, the internal lubricating oil slowly seeps out under pressure and evenly covers the surface of the roller body 2, thereby reducing the friction coefficient and reducing the movement resistance.

[0051] Furthermore, the mobile bracket 3 is composed of an upper beam portion, a lower beam portion and a plurality of support portions located between the upper and lower beam portions, wherein the upper beam portion, the lower beam portion and the support portion can be composed of equipment piers and support beams left over from other equipment at the construction site, and the height difference between the equipment base and the foundation elevation can be adjusted. There is no need to purchase a large amount of materials to make an overall large steel bracket. Under the premise of safety, reliability and ensuring the quality of installation, the labor, material and machinery costs for making the overall large steel structure bracket are reduced, which has the advantages of safety, speed, cost savings and improved work efficiency.

[0052] Embodiment 2

[0053] On the basis of the first embodiment, in order to ensure that the oil level in the oil supply tank 601 is within the set range and to ensure the oil supply effect of the oil supply unit 6, as shown in FIG. Figure 5-Figure 6 As shown, the length of the oil storage bin 7 is equivalent to the length of the roller body 2 and is fixed on the inner wall thereof, and a connecting pipe 701 is provided between the oil storage bin 7 and the oil supply bin 601; the refueling unit 8 is located at the end of the oil storage bin 7, and includes a first mounting seat 802 and a second mounting seat 804 fixed on the inner wall of the roller body 2; the first mounting seat 802 is fixed with an air pump 801 and a first metal sheet 803 for inflating the oil storage bin 7, and the second mounting seat 804 is penetrated by a movable rod 805, one end of the movable rod 805 is fixed with a second metal sheet 806 that cooperates with the first metal sheet 803, and the other end is fixed with a magnetic block 807, and a second spring 808 is sleeved on the movable rod 805 between the magnetic block 807 and the second mounting seat 804; the refueling unit 8 also includes a magnetic plate 809 fixed on the limit plate 5, and the magnetic plate 809 repels the magnetic block 807 to drive the second metal sheet 806 to contact the first metal sheet 803.

[0054] The roller body 2 drives the oiling unit 8 to rotate when rolling. When the magnetic block 807 rotates to be flush with the magnetic plate 809, the magnetic block 807 and the movable rod 805 move inward due to their repulsion. The second spring 808 is compressed, and the movable rod 805 drives the second metal sheet 806 to contact the first metal sheet 803. At this time, the circuit of the air pump 801 is connected, and the oil storage tank 7 is inflated through the air pump 801. As the pressure in the oil storage tank 7 increases, the lubricating oil is pressed into the oil supply tank 601 through the connecting pipe 701. As the roller body 2 continues to roll, When the magnetic block 807 rotates to a height different from that of the magnetic plate 809, the repulsive force disappears, and the second metal sheet 806 separates from the first metal sheet 803 under the restoring force of the second spring 808, and the air pump 801 stops inflating; the refueling unit 8 automatically refuels the oil supply bin 601 intermittently based on the rolling process of the roller body 2, and can quickly inject lubricating oil into the oil supply bin 601 without the need for complex control components, and the coating position of the oil supply unit 6 can be adapted to the pillow track 1, mobile bracket 3 and horizontal equipment 4, effectively avoiding waste of lubricating oil.

[0055] Embodiment 3

[0056] On the basis of the first and second embodiments, in order to improve the stability of the mobile bracket 3 in the stopped state, this embodiment provides a mobile bracket 3 with a frame structure, such as Figure 1 , Figure 7-Figure 8 As shown, one of the supporting parts of the mobile bracket 3 is provided with an inclined bracket 9 for limiting its movement on a layer of roller assembly, and the inclined bracket 9 includes a horizontal plate 901 and an inclined rod 902. The lower end of the supporting part of the mobile bracket 3 is provided with a first support 301, and the upper end of the supporting part of the mobile bracket 3 is provided with a second support 302. One end of the horizontal plate 901 is hinged to the first support 301, and the other end is hinged to one end of the inclined rod 902, and the other end of the inclined rod 902 is hinged to the second support 302; the inclined rod 902 includes a first rod body 902a and a second rod body 902b, and the first rod body 902a and the second rod body 902b are hinged to each other. The inclined bracket 9 can be unfolded and folded. During the movement of the mobile bracket 3, it is folded and retracted to avoid affecting the movement of the mobile bracket 3. When the mobile bracket 3 is stopped, it is unfolded to limit the mobile bracket 3 and prevent it from moving.

[0057] In order to improve the adaptability of the diagonal support frame 9 and the roller body 2, at least two clamping blocks 903 are slidably arranged in the bottom groove of the horizontal plate 901, and the bottom of the clamping block 903 is provided with a semicircular groove matching with the roller body 2. The clamping block 903 is fixed to the horizontal plate 901 by a fastener, and a second slot 904 for the fastener to pass through is provided on the side of the horizontal plate 901. The position of the clamping block 903 on the horizontal plate 901 can be freely adjusted, so as to adapt to the use of the roller body 2 in different positions.

[0058] The limit plate 5 at the first layer of roller assembly is fixedly installed on the pillow track 1, and a positioning plate 502 is provided on the inner side thereof for limiting the movement of the roller body 2 when the roller body 2 is stopped. The positioning plate 502 is fixed to the limit plate 5 by fasteners, and a first slot hole 501 for the fastener to pass through is also provided on the side of the limit plate 5.

[0059] After the mobile bracket 3 moves to the specified position on the first layer, the positioning plate 502 is fixedly installed on the limit plate 5, and the further rolling of the roller body 2 is limited by the positioning plate 502. Then the diagonal support frame 9 is unfolded, and the position of the block 903 on the cross plate 901 is adjusted. The block 903 is stuck on the roller body 2, and the movement of the mobile bracket 3 is limited by the diagonal support frame 9, thereby facilitating the movement of the second layer.

[0060] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
