Description

Technical Field

[0001] This invention relates to the field of electromechanical equipment transfer and installation technology, and specifically to a device for supporting the installation of electromechanical equipment and its operating method. Background Technology

[0002] In industrial production, engineering construction, and other fields, the installation of large-scale electromechanical equipment is a core process. Currently, the installation of large-scale electromechanical equipment generally adopts the hoisting operation mode, that is, the electromechanical equipment is lifted to the pre-set installation area by hoisting equipment, and then its position is adjusted and fixed.

[0003] The shortcomings of this work method are:

[0004] After the equipment is hoisted into place, its position needs to be adjusted by manual dragging, prying with crowbars, and other auxiliary methods. This adjustment process is not only time-consuming and labor-intensive, but also makes it difficult to accurately control the alignment accuracy between the electromechanical equipment and the installation support, affecting the efficiency and quality of equipment installation. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, this invention provides a device and its operating method for supporting the installation of electromechanical equipment.

[0006] The present invention adopts the following technical solution: a device for supporting the installation of electromechanical equipment. The chassis has outriggers fixed at each of the four corners. The support platform is fixed to the chassis; At least four rocker arms are hinged to the four corners of the chassis. Multiple rectangular Mecanum wheels are installed one-to-one on the end of the rocker arm away from the chassis; Multiple variable-amplitude hydraulic cylinders are respectively hinged between the rocker arm and the chassis; The variable-amplitude cylinder is used to control the rocker arm to switch between a first state and a second state. In the first state, the lowest position of the Mecanum wheel is lower than the lowest position of the outrigger. In the second state, the highest position of the Mecanum wheel is higher than the upper surface of the support platform.

[0007] Furthermore, a support shaft is fixed to one end of the rocker arm away from the chassis, and a Mecanum wheel, symmetrically arranged along the rocker arm, is installed at each end of the support shaft.

[0008] The rocker arm includes a forearm body and a rear arm body that are rotatably connected. The end of the forearm body away from the rear arm body is hinged to the chassis, and the luffing cylinder is hinged between the forearm body and the chassis. The support shaft is fixed at the end of the rear arm body away from the forearm body.

[0009] The forearm body and the rear arm body have mating end faces at their proximal ends; The rear arm body is provided with a mounting hole for the support shaft to pass through. The inner wall of the mounting hole is provided with a through hole that is vertical and extends through to the mating end face of the rear arm body. The inner wall of the through hole has an inner shoulder at one end near the forearm body. A blind hole opposite to the through hole is provided on the mating end face of the forearm body; A positioning post is inserted into a through hole, and one end of the positioning post near the forearm body is inserted into a blind hole and fixedly connected to the forearm body; the end of the positioning post near the rear arm body has an outer shoulder. The bearing is fitted between the locating pin and the through hole, with its two ends abutting against the inner shoulder and the outer shoulder, respectively.

[0010] Symmetrical buffer leveling cylinders are provided on both sides of the forearm body and the rear arm body. The forearm body and the rear arm body have mating end faces at their proximal ends. The upper side of the forearm body has a boss that extends toward the rear arm body and crosses the mating end face. The buffer leveling cylinder is hinged between the two sides of the boss and the two sides of the rear arm body. The axis of the buffer leveling cylinder is parallel to the mating end face.

[0011] The outrigger includes a support column fixed to the lower side of the chassis, and a universal foot plate is fixed to the lower end of the support column; in the first state, the lowest position of the Mecanum wheel of the rocker arm is lower than the lowest position of the universal foot plate.

[0012] The Mecanum wheel is connected to an independently controlled wheel-side drive.

[0013] Two positioning strips are fixed to the upper side of the chassis; Two rows of positioning blocks that cooperate with positioning strips are fixed on the lower surface of the bearing platform. The positioning blocks are attached to and fixedly connected with the positioning strips. The support platform has multiple through slots that mate with the Mecanum wheel; in the second state, the highest position of the rocker arm can pass through the through slots and be higher than the upper surface of the support platform.

[0014] An installation operation method for electromechanical equipment, employing a device for supporting the installation of electromechanical equipment, includes the following steps; S1. The rocker arm is lowered to the first state by the variable amplitude cylinder; S2. Hoist the electromechanical equipment onto the support platform; S3. The chassis moves to the support to be installed via Mecanum wheels. The position of the chassis is adjusted by controlling the steering of each Mecanum wheel so that the electromechanical equipment on the load-bearing platform is basically aligned with the support. S4. The rocker arm is gradually raised to the second state by the variable amplitude cylinder. During this process, the height of the chassis gradually decreases, first allowing the electromechanical equipment to fall onto the mounting support, then the outriggers to contact the ground, and finally the rocker arm rotates to contact the bottom surface of the electromechanical equipment and raises the electromechanical equipment to the position where it is separated from the mounting support. S5. Adjust the position of the electromechanical equipment by controlling the direction of each Mecanum wheel so that the electromechanical equipment is vertically aligned with the mounting bracket. S6. Lower the rocker arm using the luffing cylinder until the electromechanical equipment is on the mounting bracket; continue lowering the rocker arm until the Mecanum wheel contacts the ground and the outrigger platform is lifted off the ground, then control the chassis to drive out of the mounting bracket.

[0015] Furthermore, in step S4, when the electromechanical equipment is raised to the point of being detached from the mounting support, the information fed back by the level measuring device installed on the electromechanical equipment is used to independently adjust each luffing cylinder to make the electromechanical equipment level.

[0016] The beneficial effects of this invention are: By using a variable-amplitude hydraulic cylinder to drive the rocker arm to swing, the Mecanum wheel can switch between two states, respectively completing the tasks of short-distance transportation and precise placement: when in a low position, it acts as a traveling wheel, relying on the wheel-side drive to achieve flexible multi-directional movement of the entire equipment in straight, lateral, and rotation, with high transportation mobility; when in a high position, it passes through the through-slot of the carrying platform to lift the electromechanical equipment, detaches from the carrying platform to complete precise positioning. One structure takes into account the dual functions of transportation and installation, without the need to disassemble and replace tooling, thus simplifying the supporting equipment for operation; During the alignment process, the flatness of the equipment is monitored in real time with the horizontal measuring device, and each set of variable amplitude cylinders is individually controlled to complete the leveling operation, effectively eliminating installation tilt deviation; by utilizing the motion characteristics of four sets of independent and controllable Mecanum wheels, the electromechanical equipment after being lifted can be finely adjusted in the plane, accurately correcting the positional deviation between the equipment and the installation support, and improving the overall installation accuracy of the electromechanical equipment. The rocker arm adopts a segmented hinged structure, which, combined with bearings, enables flexible relative rotation. Combined with symmetrically arranged buffer and leveling cylinders, it forms a buffer and shock absorption structure, which can adapt to uneven road surfaces and reduce bumps and swaying when moving. When the jacking equipment is in operation, it can automatically fit into the bottom surface of the equipment, evenly distribute the support force, and improve the overall stability during the relocation and jacking operations.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", and "around" indicate orientation or positional relationship only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0035] Example 1: like Figures 1 to 4 As shown, the present invention provides a device for supporting the installation of electromechanical equipment 7, including a chassis 1 with outriggers 6 at four corners and a support platform 2 fixed on the chassis 1. The support platform 2 is used to support the electromechanical equipment 7. The outriggers 6 include support columns 61 fixed to the lower side of the chassis 1, and universal foot plates 62 are fixed to the lower ends of the support columns 61. A pair of rocker arms 3 are hinged to the front and rear ends of the chassis 1, and the four rocker arms 3 are distributed in a rectangle with parallel hinge axes. A Mecanum wheel 4 is installed at the end of the rocker arm 3 away from the chassis 1, and a luffing cylinder 5 is hinged between the rocker arm 3 and the support column 61; the position of the Mecanum wheel 4 can be controlled by the luffing cylinder 5, so that it can switch between two extreme positions between a first state and a second state, and can stop at any position in between.

[0036] Combined Figure 7 , Figure 8As shown, a support shaft 41 is fixed to the end of the rocker arm 3 away from the chassis 1. A Mecanum wheel 4 is mounted on each end of the support shaft 41. These two Mecanum wheels 4 form a group and are arranged symmetrically along the rocker arm 3. Each Mecanum wheel 4 is connected to an independently controlled wheel-side driver 42, which is fixed to the support shaft 41 and controls the rotation of the Mecanum wheels 4. In another embodiment, each group of Mecanum wheels 4 can be coaxially connected, so only one Mecanum wheel 4 needs to be connected to one wheel-side driver 42.

[0037] Combination Figures 1 to 6 As shown, chassis 1 has a frame structure, with the power supply and control system installed in the middle. The upper sides of the two main beams of chassis 1 have two positioning strips 11. The support platform 2 is a flat plate, with two rows of evenly distributed positioning blocks 21 fixed to its lower surface. The support platform 2 is supported on the positioning strips 11, and the positioning blocks 21 are attached to the positioning strips 11 and fixedly connected by bolts. The support platform 2 adopts an easily disassembled bolt connection structure for convenient replacement, and is used to accommodate electromechanical equipment 7 with a raised bottom surface. Through slots 22 need to be provided on the support platform 2 to correspond one-to-one with the Mecanum wheels 4. When the rocker arm 3 is in the second state, the highest position of the Mecanum wheel 4 can pass through the through slot 22 and thus be higher than the upper surface of the support platform 2, allowing it to lift the electromechanical equipment 7 on the support platform 2.

[0038] like Figure 2 , Figure 14 As shown, when the rocker arm 3 is in the first state, the lowest position of the Mecanum wheel 4 is lower than the lowest position of the support leg 6. At this time, the Mecanum wheel 4 acts as a walking wheel, which can drive the chassis 1 to move. like Figure 6 , Figure 15 As shown, when the rocker arm 3 is in the second state, the highest position of the Mecanum wheel 4 is higher than the upper surface of the bearing platform 2. At this time, the outrigger 6 supports the chassis 1, and the Mecanum wheel 4 supports the electromechanical equipment 7. By controlling the different rotation modes of the Mecanum wheel 4, the position of the electromechanical equipment 7 can be adjusted so that the electromechanical equipment 7 corresponds to the mounting bracket 8.

[0039] Example 2: Based on the above embodiment one, combined with Figures 7 to 12 As shown, in order to improve the stability of the Mecanum wheel 4 on the road and the adjustment of the electromechanical equipment 7, the rocker arm 3 in this embodiment has adaptive rotation and buffering effects. The rocker arm 3 includes a forearm body 31 and a rear arm body 32 that are rotatably connected. The near ends of the forearm body 31 and the rear arm body 32 have mating end faces that are either in contact or have a certain gap. The end of the forearm body 31 away from the rear arm body 32 is hinged to the chassis 1, and the luffing cylinder 5 is hinged between the forearm body 31 and the support column 61. The end of the rear arm body 32 away from the forearm body 31 has a mounting hole, and the support shaft 41 passes through and is fixed in the mounting hole.

[0040] The inner wall of the mounting hole of the rear arm body 32 is provided with a through hole, which is vertical and extends through to the mating end face of the rear arm body 32. The inner wall of the through hole has an integral inner shoulder 321 at one end near the forearm body 31. A blind hole coaxial with the through hole is provided on the mating end face of the forearm body 31; The positioning post 33 is inserted into the through hole through the inner wall of the mounting hole. The end of the positioning post 33 near the forearm body 31 is inserted into the blind hole. The end of the positioning post 33 near the rear arm body 32 has an integral outer shoulder 331. Multiple connecting holes are opened at the bottom of the positioning post 33 and the blind hole. Bolts are threaded into the connecting holes to fix the positioning post 33 to the forearm body 31. The bearing 34 is fixed between the positioning post 33 and the through hole, and is interference-fitted with both. The two ends of the bearing 34 abut against the inner shoulder 321 and the outer shoulder 331 respectively to achieve positioning. Under the action of the bearing 34, the forearm body 31 and the rear arm body 32 can rotate relative to each other around the positioning post 33, ultimately ensuring that the Mecanum wheel 4 contacts the ground or the bottom surface of the electromechanical equipment 7 to provide stable support.

[0041] The upper side of the forearm body 31 has a boss 311 extending towards the rear arm body 32, extending beyond the mating end face and into the upper part of the rear arm body 32. A pair of lugs are welded to both sides of the boss 311 and the rear arm body 32 respectively, and the two ends of the buffer leveling cylinder 35 are hinged to the corresponding lugs. The buffer leveling cylinders 35 on both sides are symmetrical, and the axis of the buffer leveling cylinders 35 is parallel to the mating end face; thus, when the forearm body 31 and the rear arm body 32 rotate relative to each other around the positioning post 33, the buffer leveling cylinders 35 on both sides will compress accordingly, achieving a buffering effect.

[0042] Example 3: Based on the above embodiment two, this embodiment provides an installation and operation method for electromechanical equipment 7, which uses the device in embodiment two and includes the following steps; S1. The rocker arm 3 is lowered to the first state by the variable amplitude cylinder 5; S2. Hoist the electromechanical equipment 7 onto the supporting platform 2, such as Figure 14 As shown; S3. The chassis 1 moves to the mounting support 8 via the Mecanum wheels 4. The position of the chassis 1 is adjusted by controlling the steering of each Mecanum wheel 4 so that the electromechanical equipment 7 on the bearing platform 2 is basically aligned with the mounting support 8. The specific rotation control of the four sets of Mecanum wheels 4 can realize the straight, lateral and rotary movement of the chassis 1. The position of the chassis 1 can be adjusted using this principle. S4. The rocker arm 3 is gradually raised to the second state by the luffing cylinder 5; during this process, the height of the chassis 1 gradually decreases, first causing the electromechanical equipment 7 to fall onto the mounting support 8, then the outrigger 6 to contact the ground, and finally the rocker arm 3 rotates to contact the bottom surface of the electromechanical equipment 7 and raises the electromechanical equipment 7 to a position where it is disengaged from the mounting support 8. Figure 15 As shown; S5. By controlling the steering of each Mecanum wheel 4, the position of the electromechanical equipment 7 is adjusted so that the electromechanical equipment 7 is vertically aligned with the mounting bracket 8. Consistent with the walking principle of the Mecanum wheel 4, the specific rotation control of the four sets of Mecanum wheels 4 can realize the straight, lateral and rotary movement of the electromechanical equipment 7. The position of the chassis 1 can be adjusted using this principle. In this embodiment, a level measuring device is installed on the electromechanical equipment 7. The level measuring device can monitor the level status of the electromechanical equipment 7 in real time. Based on the level information of the electromechanical equipment 7, each variable amplitude cylinder 5 can be adjusted independently to make the electromechanical equipment 7 level. After the electromechanical equipment 7 is level, the position of the chassis 1 is adjusted by the Mecanum wheel 4. S6. Synchronously control the luffing cylinder 5 to lower the rocker arm 3 until the electromechanical equipment 7 falls onto the mounting bracket 8, so that the electromechanical equipment 7 and the mounting bracket 8 are correctly aligned; continue to lower the rocker arm 3 until the Mecanum wheel 4 contacts the ground and the outrigger 6 is lifted off the ground, control the chassis 1 to drive out of the mounting bracket 8; fix the electromechanical equipment 7, and the installation is completed.
