Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and in particular to a hoisting tool for indoor electromechanical installation. Background Art

[0002] When performing indoor installation operations, it is often necessary to lift, position and install electromechanical equipment. Due to the weight of the electromechanical equipment itself and the requirements for installation height, as well as considerations for safe construction operations, it is essential to use lifting equipment for lifting. The existing lifting method for indoor electromechanical equipment installation mainly uses a light gantry for lifting. The light gantry is moved to one side of the installation location, and then the electromechanical equipment is lifted to the specified height for installation.

[0003] During the actual installation process, it is often encountered that there are steel structure beams, mounting frames of other equipment, columns, laid bridge frames, air ducts, etc. in front of, on both sides of, or above the front of the installation point of the electromechanical equipment, which makes it impossible to directly erect the gantry on one side of the installation point, resulting in a distance between the electromechanical equipment and the installation point after it is lifted. In this case, only a practical chain hoist is used for lateral tensioning, and the newly added anchor point of the chain hoist is generally set on the steel structure above the side of the installation point. If there is no steel structure above, a new anchor point needs to be added to the wall. Due to lateral tensioning, the electromechanical equipment and the gantry are easily unstable. Once the bayonet is loose, it is very easy to fall or swing sideways. There are great safety hazards in the construction process, and the tensioning and auxiliary equipment installation process is slow, affecting the efficiency of equipment installation.

[0040] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0041] like Figure 1-8 As shown, an indoor electromechanical installation hoisting device includes a mobile frame 100 and telescopic support legs 200 that are symmetrically connected to the extensions on both sides of one end of the mobile frame 100. At the same time, wheel assemblies 120 are installed on the extensions on both sides and the bottom of the right end of the mobile frame 100. The wheel assemblies 120 are installed in a three-point distribution to increase the stability of the support.

[0042] The first pivoting groove 210 of the movable frame 100 is symmetrically provided with a first rotating groove 110 opening to the right side on the extension parts of one end of the movable frame 100 to both sides. One end of the rotating plate 210 included in the telescopic support leg 200 is rotatably installed in the first rotating groove 110 through a rotating shaft. A first telescopic groove 220 opening to the rotating end is provided in the rotating plate 210. The top of the first telescopic groove 220 is connected to the limiting groove 230 that passes through the top surface of the rotating plate 210. The telescopic plate 240 is inserted into the first telescopic groove 220. The top of the telescopic plate 240 is connected to the first fixed shaft 250 that passes through the limiting groove 230. The bottom of the outer end of the telescopic plate 240 is connected to the support plate seat 241. The support adjustment member is installed on the support plate seat 241. At the same time, a universal wheel 270 is installed at the bottom of the outer end of the rotating plate 210. By providing the universal wheel 270, the stability of the telescopic plate 240 and the rotating plate 210 when subjected to the supporting force is increased, and the range of the front and rear force points is also increased, thereby further increasing the stability of the support.

[0043] A bidirectional telescopic member 300 is installed between the first fixed shafts 250 on both sides. The bidirectional telescopic member 300 controls the extension of the telescopic support legs 200 on both sides and their rotation toward both sides of the mobile frame 100. When adjusting, the bidirectional telescopic member 300 is first pulled to the right to drive the telescopic plates 240 on both sides to extend. After extending to a specified length, the support adjustment member is controlled to extend and contact the ground, thereby achieving the purpose of increasing the range of force points laterally, that is, reducing the force arm of the hoisted object at the critical rollover, reducing the torsional moment, increasing the safety and stability of the hoisting, and also increasing the range of arm extension laterally.

[0044] The middle portion of the mobile frame 100 is rotatably connected to the first boom 400 tilted to the left via the second rotating seat 140. The top of the first boom 400 is rotatably connected to the telescopic second boom 500. The second boom 500 extends to the right. The bottom of the telescopic arm 540 included in the second boom 500 is rotatably connected to the telescopic support arm 600. The bottom end of the support arm 600 passes through the first through-slot 410 provided on the first boom 400 and is rotatably connected to the mobile frame 100. The connection point is the first rotating seat 130.

[0045] A height-adjustable rotating connection base is mounted on the support arm 600. The rotating connection base is symmetrically mounted with a second rotating shaft sleeve 710 for front and rear rotation. Meanwhile, a third rotating shaft sleeve 740 is symmetrically mounted on the front and rear first fixed shafts 250. The sidewalls of the second and third rotating shaft sleeves 710 and 740 on the same side are axially connected to the ends of a third telescopic member 730 for adjusting the support angle of the support arm 600 and transmitting the supporting force to the telescopic support leg 200.

[0046] A wire-receiving hoisting unit is installed on one end of the movable frame 100 , the first boom 400 , and the second boom 500 .

[0047] Design concept: Comprehensive research considers the reasons why the existing gantry is not suitable for electromechanical hoisting installation in various environments, vertical lifting is not flexible, and its frame needs to occupy a large vertical space. The working principle of the indoor hoisting equipment proposed in the present invention is to move the hoisting equipment to the front or side of the installation point so that there are no obstacles on the extension path of the first boom 400 and the second boom 500. The two-way telescopic member 300 stretches the telescopic support legs 200 on both sides and adjusts the telescopic support legs 200 on both sides to rotate to both sides to increase the support area and extend the support point, that is, to reduce the force arm of the hoisted object at the critical rollover, reduce the torsional moment, increase the safety and stability of the hoisting, and also increase the extension range of the boom laterally, and coordinate the telescopic support legs 200 on both sides by controlling the extension of the third telescopic member 730. 00, when the two-way telescopic member 300 adjusts the rotation angle of the telescopic support legs 200 on both sides to be fixed, the support angle of the support arm 600 is controlled by controlling the extension and contraction of the third telescopic member 730, and the elevation angle of the second boom 500 is controlled by the extension and contraction of the support arm 600. Then, the extension of the telescopic arm 540 is controlled to make its top end be located above the front of the installation point. In this process, the support arm 600 extends and rotates, and the gravity of the lifting equipment is transmitted to the front and rear third telescopic members 730 and the mobile frame 100 through the support arm 600, and the third telescopic member 730 transmits the supporting force to the telescopic support legs 200 on both sides; the hoisted object can be installed before extension or lifted vertically after extension, depending on whether the vertical path in front of the installation point can meet the space for vertical lifting of the equipment.

[0048] like Figure 4 、 6As shown, the support adjustment member includes a first threaded rod 260, which is installed through a threaded hole 242 provided on the support plate seat 241. The top of the first threaded rod 260 is connected to the handle 261, and the bottom end of the first threaded rod 260 is connected to the support plate 263 through a rotating joint 262. The first threaded rod 260 is driven to rotate by rotating the handle 261, so as to achieve the purpose of controlling the bottom end of the first threaded rod 260 to extend downward and drive the support plate 263 to support on the ground, thereby achieving the purpose of increasing the support force range. After the hoisting is completed or when used as a mobile carrier, the control handle 261 is rotated in the opposite direction to retract the support plate 263.

[0049] like Figure 5 As shown, the two-way telescopic member 300 includes two first rotating sleeves 310 mounted on the front and rear first fixed shafts 250, and the side walls of the two first rotating sleeves 310 are connected to the second threaded rods 320 with opposite threads. At the same time, the inner ends of the two second threaded rods 320 are respectively threadedly connected to the two ends of the two-way threaded cylinder 330. When the two-way threaded cylinder 330 rotates, the two second threaded rods 320 are controlled to move toward or in opposite directions. By pulling the two-way threaded cylinder 330 to the right, the first fixed shafts 250 on both sides are driven to move to the right, and the first fixed shaft 250 drives the telescopic plate 240 to extend, thereby achieving the purpose of increasing the support radius. After the length adjustment is completed, the second threaded rods 320 on both sides are controlled to extend outward by rotating the two-way threaded cylinder 330, thereby completing the function of controlling the rotation support angle of the telescopic support legs 200 on both sides, increasing the lateral support width, and increasing stability during lifting or driving.

[0050] like Figure 7 As shown, a gasket 251 is installed on the first fixed shaft 250 above the first rotating sleeve 310. The gasket 251 is installed to prevent the coaxially installed first rotating sleeve 310 and the third rotating sleeve 740 from rotating and friction, which affects the rotation. The third rotating sleeve 740 is installed above the gasket 251, and a first cover 252 is installed on the top of the first fixed shaft 250. The first cover 252 is fixed to the top of the first fixed shaft 250 by screws. A fifth rotating seat 750 is provided on the side wall of the third rotating sleeve 740. The second rotating sleeve 740 is provided with a fifth rotating seat 750. A fourth rotating seat 720 is provided on the side wall of the sleeve 710, and the two ends of the third telescopic member 730 are respectively connected to the fourth rotating seat 720 and the fifth rotating seat 750 through a rotating connecting head. Since the support arm 600 and the telescopic support leg 200 can both rotate, in order to avoid the third telescopic member 730 connected and supported by them from being stuck in the rotation limit, the second rotating sleeve 710 and the third rotating sleeve 740 are provided to satisfy the two-dimensional plane rotation thereof, and at the same time, the spatial three-dimensional rotation connection is satisfied through the axial rotation connection of the side wall.

[0051] like Figure 7As shown, the support arm 600 further includes a second telescopic member 620 mounted on the top of the support frame 610. The bottom end of the second telescopic member 620 is mounted on the top of the support frame 610 through a base. The top end of the second telescopic member 620 is rotatably connected to the protrusion 541 at the bottom of the telescopic arm 540. The top end of the conventional support arm is connected to the fixed arm 510, which limits the lifting radius and load of the crane. By rotatably connecting the top end of the second telescopic member 620 to the protrusion 541 at the bottom of the telescopic arm 540, the support radius is increased, thereby increasing the lifting radius and the lifting load.

[0052] A rotating connecting seat is installed on the top of the support frame 610, and the rotating connecting seat includes a kit 630. The kit 630 is symmetrically connected to the second fixed shaft 640 front and back. The second rotating sleeve 710 is rotatably installed on the second fixed shaft 640. At the same time, a second cover 641 is installed on the outer end of the second fixed shaft 640. The second cover 641 is installed on the outer end of the second fixed shaft 640 by screws to prevent the second rotating sleeve 710 from falling off.

[0053] like Figure 8 As shown, the second boom 500 further includes a fixed arm 510, one end of the fixed arm 510 is hinged to the top of the first boom 400, a second telescopic slot 511 is provided in the fixed arm 510 that passes through the other end, and the bottom of the second telescopic slot 511 is connected to a second through slot 512 that passes through the bottom and outer end of the fixed arm 510, one end of the telescopic arm 540 is slidably inserted into the second telescopic slot 511, and a protrusion 541 provided at the bottom of the telescopic arm 540 passes through the second through slot 512, and the fixed arm 5 10 A first telescopic member 530 is installed at the lower left side, and the telescopic arm 540 is controlled by the first telescopic member 530. With the support of the second telescopic member 620, the stability of the sliding lifting is increased. The telescopic end of the first telescopic member 530 is connected to the protrusion 541, and ear plates 542 are symmetrically installed at the outer end of the telescopic arm 540. A rotating shaft 543 is installed between the ear plates 542, and a shaft cylinder 544 is installed on the rotating shaft 543. The shaft cylinder 544 is provided to reduce the resistance of the wire rope 800 to the retraction and extension.
