Description

Technical Field

[0001] The present invention belongs to the technical field of equipment hoisting in factories, and specifically relates to a device and method for lifting and placing equipment in a closed factory, which is suitable for equipment lifting and placing operations in a limited space. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention, and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] At present, with the development of industry, larger equipment is mostly presented in modular form, and the equipment manufacturing and assembly takes a long time. At the same time, because the equipment is supplied in an integral frame type, the shape of the pre-assembled set of equipment is mostly irregular during the on-site installation process. In the reconstruction and expansion projects, the main plant structure is generally not adjusted, and the replacement of equipment in the plant is carried out in a limited space. However, due to the obsolescence of the main plant, the original plant design did not consider equipment updates, or the defects of the plant height limit, the lifting operation height cannot meet the requirements, making it impossible to carry out lifting operations in the plant. Traditional construction operations often use the method of destroying large areas of walls, and then using lifting machinery to climb poles at a small angle for lifting, and cooperating with personnel to pry to complete. This method has the following problems: 1. When lifting equipment in a closed factory building, it is difficult to choose the position of the lifting machinery. It is necessary to consider the overlap between the lifting arm of the lifting machinery and the center point of the position. The angle between the crane arm and the ground is small, which may easily cause light and heavy machinery to tip over; 2. When installing equipment in a limited space, due to the lack of intuitive line of sight of the lifting machinery, it is easy for people to operate it incorrectly, which may easily cause man-made lifting accidents; 3. During the equipment replacement process, the main body of the factory building is greatly damaged, endangering the structural safety of the factory building.

[0004] In addition, if the equipment to be installed is below the horizontal elevation, the space is limited and the lifting machinery cannot cooperate to complete the lifting operation. Large-scale ground damage must be carried out and manpower must be used for hauling and installation, which is time-consuming and labor-intensive and prone to accidents where people are squeezed and injured. Summary of the invention

[0005] In order to solve the technical problems existing in the prior art, the purpose of the present invention is to provide a device and method for translating and hoisting equipment in a closed factory building. The device can realize equipment replacement operations in a closed factory building, and is particularly suitable for the installation of equipment below the horizontal elevation.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] A device for lifting and placing equipment in a closed factory building, comprising:

[0008] The support has a rectangular frame body composed of two horizontal beams and two longitudinal beams on its working surface, and multiple grooves are processed on the two horizontal beams, and the upper ends of the grooves are open;

[0009] A plurality of rollers are rollably mounted on the grooves of the two beams, the plurality of rollers are arranged in parallel, and the diameter of the rollers is less than or equal to the width of the upper opening of the groove;

[0010] A first hoisting gantry and a second hoisting gantry are both installed on the bracket, and each hoisting gantry is installed with at least one first lifting and traction device;

[0011] At least one second lifting and traction device is installed at the end of the bracket.

[0012] In some embodiments, the height of the lifting gantry is 1.5-4m.

[0013] In some embodiments, the diameter of the roller is 5-20 cm. The setting of the roller diameter is to ensure that it has sufficient supporting strength.

[0014] In some embodiments, the distance between two adjacent rollers is 10-50 cm. A smaller distance between the rollers can ensure a good conveying effect and effectively prevent the device from getting stuck during the conveying process. However, if the distance between the rollers is too small, it is easy to increase the overall cost of the device and increase the workload of the equipment hoisting process.

[0015] In some embodiments, limit blocks are respectively provided on both sides of the opening of the groove body of the crossbeam.

[0016] The limit block has a limiting effect on the roller, which can prevent the roller from slipping out of the groove during the equipment transportation process.

[0017] In some embodiments, two first lifting and traction devices are disposed on the first lifting gantry and the second lifting gantry.

[0018] Furthermore, the first lifting and traction equipment is installed at the end of the lifting gantry.

[0019] It is easier to adjust the lifting position and lifting angle of the equipment.

[0020] In some embodiments, diagonal braces are provided between the first hoisting gantry and the second hoisting gantry and the bracket.

[0021] The diagonal brace is used to fix the lifting gantry.

[0022] Furthermore, the first hoisting gantry and the second hoisting gantry are arranged in parallel.

[0023] In some embodiments, the bottom of the bracket is provided with load-bearing legs.

[0024] Furthermore, the height of the load-bearing legs is 0.2-0.5 m. The height of the load-bearing legs is relatively low, which facilitates the transport of the target device to the bracket.

[0025] A method for horizontally lifting and installing equipment in a closed factory building, comprising the following methods:

[0026] Assemble the translational lifting and positioning device at the target location;

[0027] The target equipment is moved to the translation lifting and positioning device, and the second lifting and traction equipment applies horizontal pulling force to it, so that the target equipment moves horizontally;

[0028] After the target device is moved to the target position, the first lifting and traction devices on the first lifting gantry and the second lifting gantry lift the target device, remove the rollers under the target device, and use the first lifting and traction device to slowly lower the target device. During the lowering process, the position of the target device is adjusted so that it falls exactly on the target position.

[0029] In some embodiments, after the translation lifting and positioning device is assembled, the center between the first lifting gantry and the second lifting gantry coincides with the center of the target position.

[0030] This makes it easier to position the target device accurately.

[0031] In some embodiments, during the process of slowly lowering the target device, the first lifting and traction device is used to coordinately adjust the position and angle of the target device.

[0032] The beneficial effects of the present invention are:

[0033] 1. The present invention uses loose materials for assembly and welding on site when translating, hoisting and positioning the equipment, and dismantles them on site after use without the need for large-scale hoisting equipment, thus avoiding new construction and expansion projects, and further avoiding damage to the main structure of the factory building.

[0034] 2. The translational lifting device adopted in the present invention can realize the overall translation and vertical lifting of the equipment. During the equipment replacement operation in a closed factory building, it can replace the lifting machinery for lifting operations, eliminating the difficulty in standing and the hidden dangers of small-angle lifting caused by the use of lifting machinery, and improving the safety and controllability of the lifting operation.

[0035] 3. The provision of the roller limit block in the present invention can realize the free disassembly of the roller and realize the anti-derailment tool of the equipment.

[0036] 4. In the present invention, during the equipment hoisting process, multiple lifting equipment are coordinated and adjusted, so that the adjustment of the distance and direction can be more minute, and the tool can be accurately aligned to improve the equipment installation accuracy and efficiency.

[0037] 5. The present invention can be applied to the installation of equipment below the horizontal elevation, thereby avoiding damage to the ground and reducing human resource investment. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0047] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0048] like Figure 1 and Figure 2As shown, a device for lifting and placing equipment in a closed factory building comprises: a bracket 3, whose working surface is a rectangular frame composed of two horizontal beams and two longitudinal beams, and a plurality of grooves are processed on the two horizontal beams, and the upper ends of the grooves are open;

[0049] A plurality of rollers 2 can be rotatably mounted on the trough of the two beams. The plurality of rollers are arranged in parallel, and the diameter of the rollers is less than or equal to the width of the opening at the upper end of the trough, so that the rollers can be easily removed from the trough, which is convenient for lowering the equipment.

[0050] The first hoisting gantry 5 and the second hoisting gantry are both installed on the bracket 3, and at least one first lifting and traction device is installed on each hoisting gantry; at least one second lifting and traction device is installed at the end of the bracket. The hoisting gantry is installed perpendicular to the working surface of the bracket.

[0051] The lifting and traction equipment is generally an electric winch. The electric winch is suitable for the lifting of large and medium-sized equipment.

[0052] The height of the lifting gantry is 1.5-4m, such as 1.5m, 2m, 2.5m, 3m, 3.5m, 4m, etc.

[0053] The diameter of the roller 2 is 5-20 cm, such as 5 cm, 10 cm, 15 cm, 20 cm, etc. The roller diameter is set to ensure that it has sufficient support strength. If the roller diameter is too large, it will lead to excessive material consumption, which is uneconomical.

[0054] The distance between two adjacent rollers is 10-50cm, such as 10cm, 15cm, 20cm, 25cm, 30cm, 35cm, 40cm, 45cm, 50cm. A smaller distance between rollers can ensure a good conveying effect and effectively prevent the equipment from getting stuck during the conveying process. However, if the distance between rollers is too small, it is easy to increase the overall cost of the device and increase the workload of the equipment hoisting process. Limit blocks are respectively set on both sides of the open slot of the crossbeam.

[0055] like Figure 3 As shown, limit blocks 7 are respectively arranged on both sides of the open slot of the cross beam, and the limit blocks 7 limit the rollers 2 to prevent the rollers 2 from slipping out of the slot during the transportation of the equipment.

[0056] The first hoisting gantry 5 and the second hoisting gantry are both provided with two first lifting and traction devices. The first lifting and traction devices are installed at the ends of the hoisting gantry, making it easier to adjust the hoisting position and hoisting angle of the equipment.

[0057] A diagonal brace 4 is provided between the first hoisting gantry 5 and the second hoisting gantry and the bracket for fixing the hoisting gantry. The first hoisting gantry 5 and the second hoisting gantry are arranged in parallel, which makes it easier to adjust the position and angle of the equipment.

[0058] The bottom of the bracket 3 may be provided with a load-bearing leg 1, and the setting of the load-bearing leg 1 can adjust the working surface of the bracket 3 to a horizontal plane, ensure smooth translation, and is suitable for environments with uneven ground. The height of the load-bearing leg is 0.2-0.5m, such as 0.2m, 0.3m, 0.4m, 0.5m, etc. The height of the load-bearing leg is low, which is convenient for carrying the target equipment to the bracket.

[0059] Before using the device, first select materials of matching specifications to make bracket 3 and lifting gantry according to the overall dimensions of the equipment and site conditions. When selecting the material of the load-bearing legs 1, the corresponding specifications should be selected after comprehensive consideration of the overall weight of the device itself and the quality of the equipment to be hoisted. The three parts are welded on site. During welding, the bracket 3 is erected and welded according to the longitudinal center line of the base of the equipment to be installed, and it is ensured that the center line of the bracket 3 coincides with the center line of the installed equipment, and the lifting gantry is reinforced by the diagonal brace 4. After the overall framework is completed, the roller limit block and roller 2 are installed. The roller limit block 7 is close to the roller without affecting the rotation of the roller 2. The top of the limit block 7 is open, and the roller 2 can be disassembled at any time. Then the suspension point of the second lifting and traction equipment 8 is selected. The equipment slides on the roller, and the required horizontal traction force is small, so the suspension point can be directly set on the bracket 3. The lifting gantry is mainly used for the vertical movement of equipment. The weight of the equipment and lifting slings must be considered during its manufacture and setting of lifting points. When in use, two lifting points are generally set on each of the two sets of lifting gantries, and the profiles are tied with wire ropes or slings.

[0060] After installation, the equipment is first hoisted onto the roller 2, and then the lifting and traction equipment on the hoisting gantry is connected to the equipment (as a precautionary measure). Then the second lifting and traction equipment 8 in the horizontal direction is connected to the equipment, and the equipment is gradually moved to the waiting position through the traction of the first lifting and traction equipment 6; during the traction process, since the roller limit block is installed on the bracket 3 and is higher than the roller 2 by a certain height, the equipment always moves within the range of the guide rail bracket during the traction process (such as Figure 4 As shown). When the equipment reaches the designated position, remove the second lifting and traction device 8 in the horizontal direction, and lift the equipment slightly by hoisting the first lifting and traction device 6 on the gantry. Retest the performance of the first lifting and traction device 6. After the test is qualified, remove the roller 2 directly below the equipment, and slowly lower the equipment to the installation position by the first lifting and traction device 6. Then make fine adjustments by the first lifting and traction devices 6 at the four corners to make it meet the installation requirements (such as Figure 5 as shown).

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
